Match My Fraction!

Right now in third grade our unit focus is all about fractions. We just learned about how to plot fractions on a number line, and what better way to practice our skills than to match mine! Match mine is similar to the game of Battleship in the way both students are facing each other and cannot see the other person’s board. We had pre-made points labeled with letters on the number lines, where one student would pick a point and need to describe it to their partner.

Using math vocabulary of greater than, less than, equal to, denominator, and numerator, students were tasked with describing their fraction point to their partner without saying what the numerator or denominator are. So for example, if plot A was on the fraction ¼, their partner might give clues such as “My fraction is on the number line with four equal parts and is less than ½.” This clue told the partner which fraction number line it was on and narrowed it down to a fraction on that line less than ½. Once they think they got it, players tell them what plot letter they thought it was and removed the privacy folder to check.
