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.
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.
What information do you need to solve the problem?
There are 19 Almond Joy and 21 Kit Kats.
Share your strategies:
Possibilities include Jumping from 21 to 31 and adding 9.
Adding 9 and 1 to get a ten and then 3 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.

The second strategy is not correct(Adding 9 and 1 to get a ten and then 5 more tens) You should add 3 more tens not 5 tens.
Thank you so much for finding that! I am fixing it now!
