How to Make the Valentine’s Roll and Graph Activity

1. Download and print the digital PDF.
The pdf has five pages. One is the size chart. The other pages have 8 sets of different sized pictures on them.
You’ll need at least one size chart for each seat at your math center.
2. Cut out each of the different sized pictures.
If you want to make this activity reusable, then laminate all of the different pieces. This will give them the added strength to last year after year.
How to Play

1. Pick up one set of pictures.
A set is one where all three cards have the same picture but the sizes are different.
2. Lay the pictures next to each other and find the smallest one.
3. Place the smallest picture in the column labeled “Small”. The biggest picture in the column labeled “Big” and the remaining picture in the column labeled “Medium”.
4. Repeat steps 1 – 3 with all of the sets of pictures.
