# Corey’s Pretend Party, Take Two

## The Activities

1. Topic: Multiplication: Book: Too Many Kangaroo Things To Do by Murphy.
2. Topic: Charts: Planning Corey’s pretend birthday party.  Kids will come up with possible venues, drinks, snacks, games for my birthday. Then we’ll all vote on them using different types of charts: bar chart, ranking charts, X votes, tick marks.  Then we’ll figure out the winners and compare to last year’s results for my pretend party

What game should we play at my party? Robot Turtles, Busytown, or the Adding Game?

3. Topic Story Problems: Solve Corey’s 6 birthday problems (I recently turned 34). We had 6 kids at circle, so team #1 solved problems A – C, and team #2 worked on D – F.
1. Corey moved to California when she was 18.  How many years ago was that?
2. Daisies have 10 petals. Roses have 7 petals. Corey has 34 petals. What flowers does she have?
3. It’s impossible to make a square out of 34 cubes. How many more cubes do you need to be able to make a square?
4. I get \$4 per week. I really want to buy a book that costs \$34. How many weeks do I have to save?
5. David is turning 34 in November. How many more months does he have to wait for his party?
6. Make a rectangle out of 34 squares. How long are the two sides of the rectangle?

## Preparation

Before circle, I use graph paper and sharpies to make the various empty charts.  I also came up with the birthday story problems.

## How did it go?

#### The Pretend Party

The kids really enjoyed coming up with choices for each chart. They listened carefully while I explained how to vote on each chart, and happily took the charts around to the parents and other kids to get their votes.  They were a bit wild while we figured out who had won, and I warned some of them for singing during the wrap-up.

The only tricky chart was the ranking chart, where you ranked your drink choices with 1,2, and 3.  I asked the kids how you could tell who won that one.  One kid said it should be the one that got the most #1s.  Another kid said it would be the one with the highest total. The kids quickly realized it should be the lowest total.

#### Birthday Story Problems

The kids were in two teams of three. One of the kids was not paying attention but did not disrupt the other two teammembers.  All the other kids worked hard on these.

Corey moved to California when she was 18.  How many years ago was that?

This was the hardest for the kids.  I suggested they should make 34 to figure it out.  After collecting 34 blocks, the kids removed 18, and then counted the remaining 16.

Daisies have 10 petals. Roses have 7 petals. Corey has 34 petals. What flowers does she have?

First the kids tried 3 10s, but they saw they couldn’t get 34.  They were a bit puzzled, so I hinted that maybe they could not use 3 daisies.  Then they switched to 1 daisy and 1 rose.  Kid #2 added another daisy = 27.  Kid #3 added another daisy: 37.  They all took away that daisy and Kid #1 suggested trying a rose instead, and they got 34!

It’s impossible to make a square out of 34 cubes. How many more cubes do you need to be able to make a square?

The kids worked together to make a 5×6 shape.  I pointed out that a square has to have the same length sides, and then they added in the last 4 blocks and saw they needed 2 more.

I get \$4 per week. I really want to buy a book that costs \$34. How many weeks do I have to save?

First Kid #4 tried to solve it by counting by 4s but they got a bit turned around and didn’t know how many they had counted.  Then Kid #4 and #5 made groups of 4s, and counted together by 4s until they got to 36.  I asked what the answer was, and the kids counted the groups and got 9, with \$2 left over.

One of the kids was having some trouble, and said, “I can’t solve this problem because I haven’t learned money yet.”

David is turning 34 in November. How many more months does he have to wait for his party?

This was very easy for them. The only problem was they didn’t initially know what month to start with.  I asked them what month it is right now, and one kid said March. Then the kids said the months in order together while one of them counted on her fingers.

Make a rectangle out of 34 squares. How long are the two sides of the rectangle?

Unfortunately I only had enough Base Ten Blocks for one set per group, so one kid worked on this while the others watched.
