Stage 3: The Empty Number Line
Most children should be able to use an empty number line for division by Year 3. These recordings help to support mental strategies.
Children will continue to use repeated addition and subtraction but will progress onto using a blank number line:
How many 4’s are in 24?
Becoming more efficient using a numberline:
Children need to be able to partition the dividend in different ways.
Children should also move onto calculations involving remainders.
A car holds 4 people. How many cars are needed to transport 49 people? (group and round up)
It is important that children continue to explore division as sharing and grouping, and to represent calculations on a numberline until they have a secure understanding.
The use of the bar model is another useful way of demonstrating division in a visual way.
How many groups of 2 in 18?
