Keywords

Multiple - A multiple is the result of multiplying a number by an integer (not by a fraction).
Gridlines - A gridline is a horizontal or vertical line that helps organise data on a graph or chart.

Common misconception

Pupils misread the values of bars on each graph.

Encourage pupils to mark on as many gridlines that they can for themselves once they have recognised the size of the whole. This may then help pupils to estimate the value of each bar more accurately until they can do it by imagining the gridlines.

This lesson follows a very similar structure to the previous lesson. Once completed, you could link together the findings from both lessons, considering the relationship between common partitions of 10,000 and 100,000 as well.

Q1.
What is the value of each part of this bar model?

Correct Answer: 50,000

Q2.
Tick the equations that match this bar model.

2,000 × 4 = 100,000

Correct answer: 2,000 × 5 = 10,000

Correct answer: 2,000 + 2,000 + 2,000 + 2,000 + 2,000 = 10,000

100,000 ÷ 5 = 2,000

Q3.
What is the value of each part in the bar model?

Correct Answer: 25,000

Q4.
Tick the sequences that go up in steps of 25,000

0 $$\quad$$ 125,000 $$\quad$$ 250,000 $$\quad$$ 375,000

25,000 $$\quad$$ 50,000 $$\quad$$ 75,000 $$\quad$$ 90,000
