apply basic facts to a graphing activity

square grid paper
In this activity, students generate interesting geometric designs from number patterns. They begin with the number on the horizontal axis (x-axis) and connect it to the value on the vertical axis (y-axis). This is the conventional order for graphing algebraic equations.
In question 1, the sums for 10 create a symmetrical curve. A visual device, the tens triangle, can also help students to learn the number combinations that add to 10.
The curve in question 2 is generated from factors of 24. This curve is also symmetrical, so drawing the curve may help students find any missing factors.
Students will find that joining the numbers in question 3 creates a series of parallel lines. Ask students why they think the lines are parallel.
These patterns could also be made by using nails and coloured string on a board.
