*101    9   *624

Choose a number on the board. X or ÷ by another number on the board AND locate the answer in the
board to make an equation. (Also use the terms “product” and “quotient” with the students as another
relationship connection.) Example: 4 x 15 = 60
If the student can use 4 numbers – they get to also use addition and score a BONUS point. Eg: 7 x 4 = 20 + 8
If a student uses a number with a * beside in the equation, they get a BONUS point.
Only one response per student.
500 x 100 x 20 x 10 = 1000 000 student will get DOUBLE BONUS points as they have used more than 4 terms
and one had a *.
Alternatively – determine your own scoring system.
Start with students finding 10 equations. Give them time to work independently to create a couple of
options and they need to try and maximise their points.
If students are capable, they can use numbers as powers (indices) too.
