Group Problem Solving I love to see mathematicians woking together, sharing strategies, and justifying their thinking. Students had a multi-step problem to solve that involved addition and subtraction with regrouping. They used strip diagrams to organize their thinking which wasn't as easy as they thought. Working Hard on Our Narrative Drafts Collecting Data About Car Colors in the Parking Lot As part of our spiral review, we gathered data about car colors in the front and back parking lots. We wanted to know if there are certain car colors that are more popular, and if so, why? After recording data on both parking lots, we noticed there are a lot of silver and white cars. So far, the kiddos have a few theories including people want cars that aren't regular colors, (as in not blue, green, orange, purple, red, yellow, or pink). Interesting theory! Next week, we'll graph our results. Using Base Ten Blocks to Model Subtraction with Regrouping Exploring Mixtures We had soooo much fun observing and separating mixtures at our mixture stations. The kiddos noticed that all the mixtures were different and could be separated using different tools. This was a great opportunity to use the microscopes to observe a mixture up close, (it didn't look like a mixture at first). You might want to find some mixtures at your house with your child and think of ways to separate the mixture. Subtraction Number Talk Here is an example of a subtraction number talk that shows student thinking. You might notice that the student recorded in red revised his thinking as he explained. Hooray! We know mathematicians revise their thinking and that helps their brain grow and learn. The other two photos are creatures a few kiddos created during recess. No, they have nothing to do with the number talk, but they are cool and I didn't want to create a gallery just for them. Making a Yummy Mixture We learned that a mixture is a two or more substances combined where their physical properties stay the same. Everyone enjoyed eating their mixture after separating it and recording observations. Addition Strategies
