Here is a set of 132 addition number bond clip cards for sums to 10. They are simple and easy to use. Just laminate & cut apart.
All sums are included in every way possible. For example: 3+?=5, ?+2=5, and 3+2=?
Throw them all in a bucket and use as a math center, or separate the cards depending on what you are covering – so you can sort out the doubles facts, the missing addends, the one more sums, the sums of 5, or the sums of 10 for a smaller, more focused center. To make it into a self-checking center, just place a dot on the correct answer on the back side of the cards. To make it a challenge, give the kiddos a stopwatch and see how fast they can finish a set.
Thanks for looking!
