Where is it hiding?

A game of probability with Mrs. Vaage's Grade Ones

We began a study in Aboriginal culture for our Social Unit of "Other Canadian Families." In one of the resource books, we discovered that some Natives played a game of hiding something under one of three containers - a type of guessing game. We decided to undertake this project for this unit. 

Each child had 3 tin cans which they covered with paper. This in itself was a great measurement activity - they discovered that they needed a rectangular piece of paper to cover a cylinder. They also covered the top of the can, which was dealing with circumference and area of a square - in an exploratory experience. The children decorated their cans with drawings and appliquéd materials. Finally, we covered the sides of the cans with clear mactac for durability. The children chose any item to use to hide. As soon as they had finished their cans, they started to play. The only instructions that they were given was to have a sheet of paper to record how many times they guessed which can, or how many times they guessed a wrong can. They were told to hide their eyes, and that they couldn't touch the cans before they made their guess.

Following are pictures to show our learning.

This pair was discovering that it was more likely to have a wrong guess.

This pair discovered that subtle clues and peeking helped the odds of having a correct guess!

This pair discerned whether the guess was "correct" or "incorrect," so they double qualified their answers.

This pair set up the parameters of the game in advance with their dots. This was their prediction of what space they would need to record their good guesses as compared to incorrect guesses.

The children discovered the fun in probability and were excited to take the game home to teach to their parents and siblings. The only condition was that they had to record the answers.

I would definitely recommend this as a highly successful math activity that is easy to do, child friendly and has hours of follow-up integration and internalization possibilities.
