I picked up some Halloween candy today for a task I’ve been wanting to create. 2/$6 at Walgreens…what a bargain! This task addresses standard 2.NBT.B.5. However, the bags offered an excellent surprise in that they provided a great example of making ten as well.

## Act 1

What do you notice? What do you wonder?

About how many candy bars do you think are in the bowl? Give a too high and a too low estimate.

## Act 2

What information do you need to solve the problem?

### There are 19 Almond Joy and 21 Kit Kats.

## Act 3

### Share your strategies:

Possibilities include Jumping from 21 to 31 and adding 9.

Adding 9 and 1 to get a ten and then 5 more tens.

Jumping from 19 to 29 then 39 and adding 1.

Adding 1 ten and 2 tens to get 30 and then adding 1 and 9.
