SMMART MATH:
Halloween Estimation

So your little Goblin is going to scare his way door to door this Halloween and come back home with a stash of candy...hmmmm...what to do?

There are a few methods of consumption that I've experienced or heard about:
-Let your kids eat their guts out on Halloween night and then ask them to select 20 more pieces to keep for future treats.
-Your children sort out the types of candy into piles and then only keep the piles of the candy that they really like.
-Turn in your candy for money at certain dentist offices.
-Your children gorge themselves on candy Halloween night and then leave the rest of the candy as an offering to the "switch witch" who, in exchange the next morning, leaves a nice gift for each child.
...I'm sure there are many options...but I like having my kiddos work for their candy!

For example, in subsequent days when your child asks for a few pieces of candy, first have them spell a word to you.  Have your child answer a math problem or recite a poem or scripture.

How about trying out this Estimation Activity?
Let your little Gobblins pour out their candy stash on the table. Then have them sort their candy by name/type.  Ask your child to estimate how many pieces of camdy are in each pile.  Write down everyone's guess.  Have your child count out each piece in a pile and write the name of the candy and how many are in the pile (great spelling/handwriting and number writing opportunity).

Have your child compare what they guessed to the actual number of candy in each pile.
Your child can write math phrases showing how their guess compared to the actual number of pieces:
-Greater than/Less than practice: "17 is more than 12"
-Subtraction practice to determine how off their guess was: "17-12=5"

Compare everyone's guess to see who came closest to the actual number of candy in each pile.  It's fun to see who comes closest to guessing correctly.

After all of that math work, reward your child with...yes, of course, a piece of candy!
