Tuesday
Learning Targets: I can solve a problem with a missing part. I can follow the problem-solving process. Everyone together: Solve a story problem on the rug. Go through the problem-solving process as a class. Ask for different ways to solve it, and put them on a poster. Get at least 4 or 5 ways. (Counting up, using the number line, counting back, using tens and ones, writing equations to landmark numbers, jumping to landmark numbers on the hundreds chart)

Tell students they need to solve each problem in //two// different ways. This is how they can double-check, and it's a way to try new strategies out that they aren't so sure about. Remind them to "think addition": what goes with __to make__ ? The new worksheets will have a place to write this sentence, and two spaces to solve the problem.

Hang the poster up where everyone can see it while they work.

Wednesday
Last day of missing part story problems (for now). Students try to work independently, and get feedback at the end of a problem.

Remind them to try two strategies. They don't have to be experts at using friendly numbers, but they should try it.

Go over the strategy options by trying out a problem as a class at the beginning. Have the fives and tens highlighted on the hundreds chart. Practice seeing how far a number is from different friendly numbers, so they understand what a friendly number is.

Thursday
Assessment on story problems.

Friday
Basic facts practice.

students are given a fact family, they write a problem to go with it.

practice as a whole group, then let them try it.
