I created this activity to help some of my students understand the concept of ten more/ less more easily.
It aligns with common core standard: CC1NBT.5
Included in this activity:
* 2 sets of number cards adding multiples of ten
(8 cards for each pattern)
* 2 sets of number cards subtracting multiples of ten
( 8 cards for each pattern)
* recording sheet for students to record their work & space for students to show their thinking.
I hope that you find it helpful!
