Elaboration on this Achievement Objective

This means students will know basic multiplication facts are those that range from 0 x 0 = 0 to 9 x 9 = 81. The division basic facts are the inverse of the multiplication facts. So 6 x 4 = 24, 4 x 6 = 24, 24 ÷ 6 = 4 and 24 ÷ 4 = 6 are all basic facts. Students should commit their basic facts to memory as soon as they understand the meaning of the equations and can use number properties to work them out, 8 x 7 = 56 means "eight sets of seven" and can be worked out by doubling 4 x 7 = 28. Note that 56 ÷ 7 can mean "fifty-six shared among seven" or "how many sevens are in fifty-six".

Times less

Level Three

Number and Algebra

The purpose of this activity is to support students in recognising that scaling applies to comparisons where one amount is less than another. For example, a 3-stack of cubes is “four times less” than a 12-stack of cubes. The use of “times” (relating to division) in such situations may seem counter...
