Learn

Students can get accustomed to plotting numbers on this large number line, and demonstrate their understanding of addition, subtraction, multiplication, and division using number lines.  The number plane or Cartesian plane is like two number lines that cross at zero; one of them is horizontal and the other is vertical. This Cartesian coordinate mat will make plotting points a lot more visual and fun.

See one of the games we play at schools under the Learn button below.

Grade Levels: 4-8

Game activities included:

Battleship
Materials needed:
Checkers or game markers in two colours

Post-it notes with letters (one for each letter of the alphabet).
Activity cards with statements
I have T, Who has (3,6) Note: H is on the coordinates (3,6)
I have H, Who has (9,0) Note: E is on the coordinates (9,0)
I have E, Who has (6,2) etc.

Four in a Row!
Materials needed:
Checkers/game markers in two colours
Deck of cards with face cards removed
Quadrant 1 on a cartesian grid

Countdown!
