Differentiation for Ordered Pairs
Support
· Students define terms by matching them with a label.
· Have students write the following words on cards: coordinate grid, x axis, y axis, x coordinate, y coordinate, origin
· Display a coordinate grid and point to its parts
· Have students hold up the flash card that describes each part
Extend
· Give each student in a pair a copy of a quadrant grid. Have students color two consecutive squares on the grid. Have students color two more pairs of squares. The colored areas are “treasures”. The students should hide their grids from their partner.
· In turn, students call out ordered pairs. If the ordered pair lies on the border of a colored square, the partner should say, “You found a treasure.” That student then plots that point on his or her grid. When a player finds all the points forming a square, that player gets the treasure. The winner of the game is the first student to get all three of his or her partner’s treasures.
On Target
- Move desks into rows and columns. Use masking tape to show the edge of the “desk grid” and label the rows and columns.
- Have the form line at (0,0). Have each student use the grid to walk back to his or her desk. Then have them say the ordered pair for the location of the desk.
Support
- Give one coordinate grid to each kid
- As you call out moves on the grid, have them use their index fingers to follow directions
- Place finger on (0,0). This point is called the origin. Move your finger 3 spaces right. At what number on the x axis does your finger stop? Now move up 4 spaces. Look at y axis. What is the number?
