There's nothing like a parent-teacher conference to
inspire new deceptively educational games. That was the case with this activity.
My son's teacher mentioned that fractions of groups was on the lesson plan for
the final trimester and that it can often be a struggle for kids.
Here's the little game I cooked up to help my son master
this skill.
Not knowing how much he'd need to be challenged, I
created one card game with three levels of difficulty. (Click on the level or the cards below to download a 3-page PDF of each.)
Level 1 is the
easiest with a grid of squares, with the representative fraction of them filled
in.
Level 2
provides the same visual cues (a grid of squares) that Level 1 provides, but
the representative fraction of squares is NOT filled in.
Level 3 is the
most challenging. There are no visual cues to help players. They must think
through the problem in their heads.
How to Play
Playing is simple. Get some glass babbles (those
flattened marbles from the craft store floral department) to use as a
manipulative. One by one players take turns, turning over the cards in the deck (print 2-3
copies of the level of your choice or mix them together) and solve the problem.
If the player answers correctly, they get to take the number of babbles in the answer. Colored cards have high-number answers.
But, wait, there are some "Put Back" cards in
the deck!! If a player gets one of these cards, when they solve the problem, the
answer is the number of babbles they must return to the "draw" pile
of babbles. If they don't have enough, they just put back all that they have.
How to Win
The first player to get 50 babbles wins (or if you're
having tons of fun, play until 100 like my son and I did). Encourage players to
put their babbles in groups of ten to make counting them easier.
