One of the visual tools your child will use in Kindergarten is the 10-frame card. Your child will know a 10-frame card has five on top and 5 on bottom. It is important he understands five without needing to re-count each time.
Let’s count out 5. One, two, three, four, five. How many more do we need to make eight? To show eight, your child doesn’t have to re-count, because can count on from five. Five… six, seven, eight! Three more are needed to make eight.
After lots of practice with 10-frames, look at all the number sense your child can pull from this tool! He can use visuals to add and take-away. For example, how many do you add to five to make eight? What is eight take-away four?
Ten-frames are also a great way to practice making ten. Ask your child, how many do you see? Eight! How many boxes are empty Two! The 10-frame card shows that eight’s missing number partner is two. Your child can see that 8 + 2 = 10 or 10 – 8 = 2.
Your child will continue using 10- frames with addition and subtraction, all the way through to learning fractions and reducing equivalent fractions.
Kindergarten Common Core Standards
Operations & Algebraic Thinking: Understanding addition as putting together and adding to, and understanding subtraction as taking apart and taking from.
(K.OA.1) Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g. claps), acting out situations, verbal explanations, expressions, or equations.
(K.OA.2) Solve addition and subtraction word problems, and add and subtract within 10, e.g. by using objects or drawings to represent the problem.
