Ladders and slides
Overview | Resources |
An activity on the multiplicative relationships between sets of numbers. The aim is for pupils to notice that the numbers in one set are constant multiples of the numbers in another set, rather than viewing them as results of repeated addition. | Lists A-D of numbers (see below) or OHT or whiteboard Paper and Blu-tack to cover numbers in the lists Worksheets 1-4 |
Aims | Curriculum links |
|
Use direct proportion in simple contexts. |
EPISODE 1 | |
Ladders - exploring the relationships between lists of multiples | |
Sharing descriptions of each set of multiples in a ‘ladder’ then looking at the relationships between two sets at a time. This is begun with the whole class, then continued in pairs using Worksheet 1. For an advanced class, Worksheet 4 could be used. | ![]() |
EPISODE 2 | |
Slides - exploring multiplicative relationships in a visual setting | |
Using the diagram on Worksheet 2, pupils construct verticals and fill in the table of results. They work out the relationships between the sets of numbers. |

EPISODE 3 (EXTENSION) | |
Using ratio for finding heights of buildings | |
