**9:55 Large-group story problem**
There were some bees in a hive. Then some flew out. How many bees were there altogether? Will there be more or less? Will we add or subtract? Remember to make a picture in your mind of the problem. Now here's the story again with numbers: There were 12 bees in a hive. Then 9 more flew away. How many bees were there altogether? Solve and write equations.

**10:05 Trading Game** **All Together**
Again, play the trading game altogether at first, starting where we left off yesterday. After about 5 turns, send them off in pairs to keep going. Remind them that they can try to get as far as possible!

**9:55 Story problem**
Same problem as above, but with smaller numbers (use 10 and 6).

Put out 10 pennies in a pile (so they can't count them) and write their estimates of how many there are. Count them together. As you get close to their estimates, ask if anyone wants to change their estimate. (For example, if someone estimates 5, after you count 4, ask if anyone wants to change their estimate to see if they notice that there are definitely more than 1 left to count). See if you have a group of 10 and talk about how many tens and how many extras there are.

10:15 Making Groups of 10
Use a problem about having 10 flowers and 2 vases. Ask them to find different ways to put the flowers into the two vases.


 * Give 2 acorns each to 4 children. Have them estimate how many acrorns there are without counting. Then count them. Ask: "How many acorns are there? How many groups of acorns are there? How many children with acorns are there?" If there's time, change the number of acorns and try again.**
