Coordinates of a point

Coordinates of a point: a free Grade 5 math game for ages 10-11. Kids move right and up from (0, 0) and pick the ordered pair that names the point. Each round brings 10 fresh questions with new numbers; instructions are read aloud and every answer is checked.

How it plays and why it helps

A grid on a board game, a square on a map, a seat in a theater: finding a spot means giving two numbers in the right order. Coordinates of a point turns that into one instruction per card, start at (0, 0), go 5 units right and 4 units up, with three ordered pairs to choose from. Ten cards make a round in this Grade 5 game, with numbers drawn fresh each time, so a repeat can turn up. Each tap is checked.

An ordered pair is ordered for a reason. The first number says how far to go right, along the x-axis; the second says how far up. The hint repeats exactly that. Every card offers the same pair switched around, so (4, 5) sits next to (5, 4), and reading the instruction in order is the whole skill.

One choice adds a step to each number. For 5 right and 4 up, (6, 5) is there, the pair a child gets by counting the starting point as 1. Ask, "Is the corner your first step, or zero?" Then count the jumps, not the dots. Close with, "You started counting from zero."
