This resources pack introduces pupils to the idea of repeating patterns of an ABAB design, and then to an AABAAB design. Pupils look at colour patterns, shape patterns and picture patterns using Welsh emblems. They have the opportunity to finish Read More …
Investigate patterns using different attributes – shape, size and colour.
Number sequences in a grid, patterns and explanations, odd and even, extend number sequences.
