# NA3-2: Know basic multiplication and division facts.

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".

Teaching resources for this Achievement Objective:

## Roughly how many?

• Numeracy activities
• Number and Algebra
• Level Three

In this activity we look at cubes which have been roughly sorted into arrays and decide about how many there are. We use our knowledge of multiplication facts to estimate the number of cubes.

## Multiple Patterns

• Numeracy activities
• Number and Algebra
• Level Three

In this activity we use a 1-100 grid to identify multiples of single digit numbers.  In particular we are looking for patterns and how they could be used to identify multiples.

## Smiley Hundred

• Numeracy activities
• Number and Algebra
• Level Three

In this activity students are encouraged to solve multiplication problems by deriving from known facts, looking for groupings and skip counting.  Students are encouraged to explain and share their thinking.

## Blank Grids

• Numeracy activities
• Number and Algebra
• Level Three

In this activity students are encouraged to view the multiplication grid in the same way that they would view a hundreds array and to consider how they will find an answer to multiplication problems by deriving from known facts, looking for groups and skip counting.

## Array game
