Join and Separate Groups

Bunnies hop together and birds fly away. Children act out and solve put-together and take-away stories with totals up to ten, and learn that every story has a first, a then and a now, ending with more or fewer than it started. No plus or minus signs yet: just objects, pictures and words.

What learners will discover

  • Solve put-together stories with totals up to ten by joining the groups and counting all.
  • Solve take-away stories within ten by removing some and counting what is left.
  • Tell a joining or separating story in order (first, then, now) and say whether there are more or fewer at the end.
