WALT: use doubles to work out word problems greater than 10.
Which double would you use? Tell your buddy.
1. There were 8 lollipops in a jar and James put in another 7. How many lollipops are in the jar now?
2. If there were 6 horses in a field and 5 more joined them. How many horses are there in the field now?
3. If there were 9 soccer balls in the bag and Sully put another 8 in. How many soccer balls are there altogether?
1+1=2 2+2=4 3+3=6 4+4=8 5+5=10
6+6=12 7+7=14 8+8=16 9+9=18 10+10=20
Do you know all these doubles? Learn them so you can use them to solve problems.
