Begin with story problem on the rug.

“I’m going to tell you a story, but you won’t be able to solve the problem right away. We’re just going to think about if we will add some or take some away, if it will be addition or subtraction.

“There were some frogs sitting on Lilly pads in the pond. Then some more frogs came to sit with them. How many frogs were sitting on Lilly pads in the pond?

“Now, do we need to add more frogs or take some frogs away?”

Get a few opinions, then tell it again with numbers.

“There were 7 frogs sitting on Lilly pads in the pond. Then 5 more frogs came to sit with them. How many frogs were sitting on Lilly pads in the pond?”

Get solutions, then put the frogs in 2 groups of 5 on Lilly pads. Ask about how many groups, how many extras, how many frogs.

CENTERS:

Some do +2 Staircases (start at 2 and go up by 2 each time, or start at 1 and go up 2 each time), then play Snap It! Others review the +1 game (making groups of 1 more than the number you pull out of the bag) and play it

A few others do ways to make 8 with a teacher

END OF CLASS:

Make a chart of ways to make 7 by organizing frogs on Lilly pads.
