Number Bonds for 10

Level 5. Number bonds for ten. In step 5, we will be learning about number bonds that equal ten. We will be using a number line. Ten bead abacus. Ten frame. Writing the number bonds as an equation. The two numbers you are adding together are add ins and the answer is the sum. We will write the addition equation two ways to illustrate the commutative property of addition. The flip flop rule. When adding two numbers together, order doesn't matter. One plus 9 is the same as 9 plus one. Then we will label a tape diagram, part to whole, and a number bond diagram. We know that zero plus ten equals ten. How many beads would we need to add to one to make ten? One, two, three, four, 5, 6, 7, 8, 9. We would add 9 to one to make ten. The community property, flip flop rule, four addition means that if one plus 9 equals ten, then 9 plus one equals ten. We can show this number bond in a tape diagram. Noticing that the whole bar represents ten, and the parts show one and 9. Go together to make ten. And a number bond diagram. We know that one and 9 equal ten. How many beads would we need to add to two to make ten? One, two, three, four, 5, 6, 7, 8. We would add 8 to two to make ten. The commutative property flip flop rule for addition means that if two plus 8 equals ten. Then 8 plus two equals ten. We can show this in a tape diagram. And in a break apart, number bond diagram. How many beads would we need to add to three to make ten? One, two, three, four, 5, 6, 7. We would add 7 to three to make ten. Remember the flip flop roll for addition means that if three plus 7 equals ten. Then 7 plus three equals ten. Write this in a tape diagram? And a number round diagram. How many beats would we need to add to four to make ten? Let's count. One, two, three, four, 5, 6. We would add 6 to four to make ten. Flip flop it. Four plus 6 equals ten and 6 plus four equals ten. Our tape diagram and a number bond diagram. How many beads would we mean to add to 5 to make ten? Let's count. One, two, three, four, 5. We would add 5 to 5 to make ten. The communicative property flip flop rule for addition means that if 5 plus 5 equals ten. Then 5 plus 5 equals ten. Represent the number bond in a tape diagram. And a number bond diagram. Let's review what we've learned. Number bonds for ten are zero and ten. One plus 9 combine to equal ten, two, plus 8 equals ten. Three and 7 equal ten. Four and 6 are add ins for ten. 5 doubled is ten.
