Answer the questions. Use anything you can to help, don’t forget to draw the tens and ones if this helps.

Mel’s house has 16 windows. Her shop has 32 windows. How many windows all together?

+ = ________

Lesson 2 -Hexagon and pentagonLO: To explore addition and subtraction.

 

Can you complete the equations using the same numbers? Remember which numbers are the whole and which are the parts.

13 + 2 = 15 15 = 13 + 22 + 13 = 15 15 = 2 + 13

15 + 4 = 19 = + + = = +

8 + 4 = 12 = + + = = +

14 + 7 = 21 = + + = = +

Now see if you can complete the equations using addition and subtraction and all the same numbers. Remember where the parts and the wholes go.

13 + 2 = 15 15 – 13 = 22 + 13 = 15 15 – 2 = 1315 = 2 + 13 13 = 15 - 215 = 13 + 2 2 = 15 – 13

15 + 4 = 19 19 - 4 = 15 + = - = = + = - = + = -

8 + 4 = 12 12 - 4 = 8 + = - = = + = - = + = -

Dan has found all of these equations using these numbers. However, he has made some mistakes.

Can you find them and correct them for him?
