Here is a quick review we did to remind them of the big ideas around fractions. The cards I used for this are from my Fourths or Not Fourths game I use with first and second graders. It is a freebie and available in this post if you want to try it out with your students.
Here is the common core standard for fractions in grade 2. These were the concepts I wanted to review and reinforce with my students
CCSS.Math.Content.2.G.A.3 Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
There were 4 kids in this booster group and we all sat around a table. I told them I wanted to talk with them about fourths and gave them each a card. I asked them to think about if their card showed fourths or not and how they knew they were right.
I saved the ones I consider the most challenging for last. I wanted to make sure the big ideas were out there first before I brought up the idea that the equal sized pieces do not have to be the same shape.
