The kids have been studying geometry in math. The kids have to know the names of solid figures, such as sphere, pyramid, cube, cylinder, cone, and rectangular prism. For each shape they have to know how many faces, edges, and vertices it has. So for Challenge Friday, our mission this week was to make one of the solid figures out of Legos and then write about it, describing it by its geometric properties. After making one, they could make another if they had time.
Although cubes, pyramids, and rectangular prisms were very popular, some kids found very creative ways to make cylinders, cones, and even spheres! We met in a share circle after every student had had a chance to make at least one shape. In the share circle, they described their shape by how many faces, vertices, and edges it had, and the other kids had to guess what shape it was. Once they guessed the correct shape, the student revealed the shape they made.
I took a picture of each shape that the kids made and then they glued the picture in their notebooks with their written descriptions.
This week we studied the word “scale” and how it’s one of those many words with multiple meanings. We read books about map scales and learned about how scale is used to determine size or distance. This led us to studying the prefix “micro” and how microscale means building a tiny version of something. The kids brainstormed other words that they were familiar with that used the prefix “micro” (such as microscope, microwave, microscopic, microbe, etc).
I informed the kids that their challenge this week was to build something with Legos in microscale. I explained that microscale in Legos is even smaller than normal Lego size. The normal scale for Legos is something built to the size of the minifigures (the little Lego people). Most cars, houses, etc are built to fit the size of the minifigures. This is called minifigure scale. Microscale for Legos would be even smaller than that. I showed them some examples that I had made of the Taj Mahal and the Washington Monument.
We also went to a website called Lego Quest Kids where there are different Lego challenges presented to kids all around the world. We looked through the selections from kids for the Microscale Challenge. Finally we looked through several Lego books, The Lego Play Book and The Lego Ideas Book to get further ideas. After seeing many examples, the kids were bubbling with excitement to try and make something in microscale as well! I gave them the choice to work alone or with a partner. They could make any object or scene that they wanted but they had to try to make it as small as possible.
Kids made models of lighthouses, cities, skyscrapers, farms, the Great Wall of China, the Eiffel Tower, and more! Some still made theirs to minifigure scale instead of true Lego microscale, but compared to the real-life versions, it was microscale!
Since we’ve been working on visualizing text all week, it seemed appropriate to make Challenge Friday somehow related to visualizing. I also needed to give the kids a quick quiz to see how they are doing with visualizing text independently. I decided to find a way to combine the two.
First, I used five different books to create leveled passages as I had done earlier in the week. Then I created two questions for each passage that were in SOL-style multiple-choice about visualization. The kids would have to answer those two questions and then draw a picture of what the text said. The questions were about the details in the passage that helped you to picture things. For example, “What detail best helps the reader to picture what the cat looks like?” and, “What did the cyclops’s voice probably sound like when he said, ‘I’ll eat you all!’?”
Some kids, who throughout the week seemed to have no problem visualizing text, had trouble with those two questions. Some didn’t understand how specific details can be used to visualize specific things. Others just didn’t read the question carefully or didn’t know what the question was asking. Their pictures were also very helpful because it showed which kids focus on one detail and ignore all the other description and action around it versus kids who notice all the details and use all of it to make their pictures. It all showed where misunderstandings were in vocabulary or phrasing of certain sentences. One student who read this sentence about a cyclops, “He was fifty feet tall,” showed a huge misunderstanding in his picture. He had drawn a dark cave, which it DID mention in the text, but in the cave was a person with a label that said, “this person walked 50 feet.” All of these observations about each student’s answers to the three parts of the quiz really helped me to see how they were visualizing and how I can help them pay attention to the details in the text better.
After I had gone over the quiz with each student, we met on the carpet to talk about challenge Friday. Their challenge today was to make the scene from the passage they had read on the quiz using Legos. It was particularly challenging because the scene that they made had to match the details from the passage that they read. I gave the passages back to them so that they could refer to them as needed. It was fun to watch how they creatively used the pieces to match the color, size, and objects from the passage. For example, one student read a passage about a man who walked through a river and was wearing heavy rain boots. She attached two blue flowers to the bottom of a Lego minifigure’s legs to be the rain boots. Other students used flagpoles and sticks as swords for their minifigure to battle a hydra.
(on a side note, doing these passages that came directly from the leveled books in my classroom library also encouraged the children to try books that they otherwise had ignored on the bookshelf. I have had many students ask me this week about where the book is that their passage came from because they would like to read the rest of it.)
We’ve been learning how to write contractions in our language arts word study time. I showed the kids how contractions work both in English and Spanish. After making a list of contractions in both languages, we compared the kinds of contractions by the rules the contractions follow in both languages. The kids noticed that, in English, contractions always use an apostrophe where the missing letter is. In Spanish, however, this is not always true. There are certain colloquialisms that do use an apostrophe when two words are put together to form a contraction, such as the words “M’ija” (mi + hija) and “pa’ que” (para + que). However there are other words that lose a letter when they make a contraction but they don’t use an apostrophe, such as “al” (a + el) and “del” (de + el). Then there are also several words that GAIN letters when they are put together, like “con” and “mi” go together to form “conmigo”. It was really interesting to watch the kids make these comparisons.
After practicing contractions for a few days, I introduced the kids to a free app for iPod touches, iPhones, and iPads. It’s called “toonthat”. It’s an app that let’s you take pictures of things and then add talking bubbles or thought bubbles and other special effects to create a comic. It’s very easy to use. The first day, we just practiced using the app and learning how to make comics. The next day, I added a requirement that their comics had to use contractions. They loved the idea!
Their comics turned out great and every day they beg me to let them make more contraction comics during their free time! They share them with their friends and make each other laugh. Some of them take pictures of each other. Others use stuffed animals as the comic characters. Still others make scenes from Legos and Playmobils and use the figures from both as the characters.
When I was introducing the app to the kids we talked about making sure to ask someone’s permission before taking a picture of them, and then make sure the comic is approved by them before showing it to anyone else. We talked about appropriate school language and what it means to be “funny at the expense of someone else”. I told them it’s much safer to use stuffed animals or toys as the characters because then you don’t have to worry as much about hurting someone’s feelings. I also shared a bunch of comics that I’ve made using my puppies and Legos as the characters.
When Lego released the series 11 minifigures, there was a yeti included as one of the 16 in the series. I knew the kids would love that one, so I collected 11 yetis (one for each pair of students) and had them participate in a Challenge Friday activity centered around the yeti. First we read about the yeti to find out what the creature is. We talked about mythical creatures and I showed the children where they could find books about the yeti and other mythical creatures if they wanted to learn more about them (which they very much did in the days to follow). Then I announced the challenge.
We talked about architects and what they do. I emphasized how architects make plans and think through what they’re going to build BEFORE the building actually happens. I explained to the kids that the yeti was hiring them as the architects and he had certain specifications that he wanted them to include. Beyond those criteria, however, they could be as creative as they wanted. They could also be creative in how they chose to include the specifications. This discussion was done in Spanish and the ideas that we we’re discussing we’re written on the board in Spanish. We’ve been talking a lot about cognates and the kids have gotten very good at identifying cognates. They immediately noticed that “arquitectos” and “plan” looked and sounded like the corresponding English words. I kept the chart paper with the specifications written in English up on the board as well so that students could refer to either language while they were making the yeti houses.
The kids set off right away, working on first a plan and then building the actual houses.
While they were building the houses, I wrote a question on the board that we would discuss during our Share Circle that would happen next.
After 20 minutes of building, the kids brought their completed houses over to the Share Circle. They thought about the answer to the question I had written on the board: “How do you know the yeti is happy with his home?” Then they shared with the partner sitting next to them. I called on several partners to share with the whole group. Some students said that they knew the yeti was happy because they “included all of the specifications” in the house, while others said it was because they had provided various forms of entertainment and comfort for the yeti, including flat screen TVs, laptops and video games, hot tubs, and heated chairs.
Finally, we went around and took a picture of each yeti house from directly above to get a bird’s-eye view. The kids went back to their tables and revised their floorplans to make sure they were accurate maps of the houses that they had created.
They really loved doing this challenge and requested to do it again the following week!
The last day of school before winter vacation is always an exciting one! The children are bouncing up and down, energy just seeping out of them. We teamed up with the class next door to create a winter holiday-themed day. While the teacher next to me had the children make gingerbread man glyphs and marshmallow towers (who could make the tallest tower out of marshmallows and toothpicks), the children in my room did Challenge Friday. The kids participated in each class’s activities and then we switched classes so that everyone could do both sets of activities.
The challenge for Challenge Friday was simple, yet meaningful, and provided the kids an opportunity to share and express their excitement for the upcoming holidays in a creative way. The challenge was to make something out of Legos that showed what they were going to do over winter break.
They had 15 minutes to build and then we made a Share Circle to show what they had made. First they shared in detail with a partner next to them, where they could show off the specific details that they included in their creation. Then we went around the circle and each child had the option to share one sentence about what they were going to do over winter break. They could also pass if they didn’t want to share.
The total amount of time for this activity was about 45 minutes – 10 min for directions and idea examples, 15 min build, 15 min Share Circle, 5 min transition time from building to coming to Share Circle.
This challenge could easily be done AFTER winter break by having kids make something they DID over the holiday vacation.)
Our final challenge for Cartober took the remaining Fridays in the month of October. The first step was making a car that would have a place to carry up to ten 50 gram Lego blocks. We raced the cars down our ramp in a hallway where the cars could roll as far as possible. We used rulers to measure the distance each car rolled.
Kids worked in groups of 3 to build their cars. Once we were ready to start racing them down the ramp and measuring the distance, the kids picked “jobs”. One kid needed to be the Measurer, one needed to be the Recorder, and one needed to be the Racer. They would switch jobs with each trial, so that each kid had a chance to measure, record, and race.
The first trial was just the car by itself with no 50 gram blocks. Each group raced, measured, and recorded. If a car broke on the way down, the group was allowed to go fix the car. On the second trial, we added one 50g block. On the third trial, we added five 50g blocks, and on the fourth trial we added ten 50g blocks.
The building of the car and doing the four trials were not done on the same day. We split it up so that the kids built a car and raced it with no 50g blocks to get their initial measurement on the first day. Then we placed the cars in gallon-size ziploc bags and I wrote each group’s names on the bag. The next Friday, we finished the trials.
After all the trials, we reflected on the effect of the added weight to the cars’ distance. We talked about what this could mean. Many kids said they were surprised that the weight would make the cars go so much faster. They had predicted that the weight would slow the cars down. Several kids remembered a field trip they took to a local ski resort in second grade to go snowtubing. They made the connection that it made sense that more weight would make something go faster because when you snowtube, you go farther if you connect more tubes together.
The kids loved Cartober and were sad to see the car racing come to an end. Little do they realize, but this will not be their last car race…. MUAH HA HA HA HA!
