7 = 4 + 3
8 = 8
4 + 5 = 5 + 4
7 + 3 = 8 + 2
If students have not seen equations written like this, and I ask them if these equations are true, they will often say no. I was thinking my first graders were getting these big ideas quite well. I decided to seize the moment and take advantage of their excitement over seeing snow and gave them a quick formative assessment on equality that happens to have a fun penguin theme.
|Students read the equations and circle T if they think the equation is true and F if they think the equation is false. If you want to try this with your own students it is a freebie at my TPT store. Click here to head over and download it!|
So I created a set of equations on cards that can be physically sorted into true and false piles. We worked on this as a whole class and I will be using the cards as part of math stations and partner/individual work time during the month of December. I will give another formative assessment after a few weeks and we will go from there.
Here is a peak at us trying it out as a whole group
|I used a pocket chart to hold the cards so everyone sitting in the discussion area could see. We only got through 8 of the 18 cards on our first attempt at this because we had so many great math discussions along the way. I pulled out the math balance during this whole group lesson and students loved using it to prove their thinking|
|This was small group work so we put the cards on the carpet.|
