The Fact Families with Sums to 20 Mathtivity Cards
is a set of 36 activity cards that have students identify and write the fact families for sums to ten and sums to 20. There are 2 sets. Each set of cards is presented in color and in black and white. The sets included in this packet are:
Set 1: Sums to 10
Set 2: Sums to 20
A recording sheet is provided for each of the card sets. The sets are already differentiated, but you can split the cards into sums to 5, sums to 10, sums to 15 and sums to 20.
Using Mathtivity Cards
These mathtivity cards can be used as a center, or you can hang them around the room and have students walk around and find the cards and record their answers on the recording sheet provided. These cards are based on the Grade 1 Ontario Mathematics expectations but both American and Canadian spelling are provided.
