There is so much we can do with these prompts! Check out fractiontalks.com for more of them, knowing that you don't need to bring up fractions; the counting and grouping is important for children to understand.
This lesson addresses the following standard:
Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
