Fill each box by multiplying its row and column numbers. Then look along a row or down a column: each step adds the same amount.
patternsomething that repeats or grows the same way
rowa line going across
columna line going down
evena number that splits into two equal groups
Watch for: Adding the row and column numbers instead of multiplying. Losing their place and reading the wrong row. Naming a pattern without checking it in the table.
At home: Ask what they notice in a times table: the 5s end in 0 or 5, and the digits of the 9s add up to 9.
