💯 Interactive Hundreds Chart: Colour, Count and Print

How to use it

1. 1. Pick your chart

   Choose 1 to 100 for the classic chart, 0 to 99 when children need to see that the tens start at 0, or 1 to 120 for a longer count.

2. 2. Colour squares by hand

   Choose a marker colour, then press squares to colour them. Press a coloured square again to clear it. Use a different colour for each pattern you want to compare.

3. 3. Highlight the multiples

   Type a number from 2 to 12 in the count by box and press Highlight. Every multiple is coloured and given a thick border, so the pattern also shows on a black and white print.

4. 4. Hide the numbers or print

   Press Hide the numbers to turn the chart into an empty grid for children to fill in. Show the numbers brings them back. Print the chart gives you the sheet on its own.

Ideas for class and home

• Skip counting patterns

  Highlight the multiples of 2, then clear and highlight 5 or 10. Children see the columns, diagonals and stripes that skip counting makes and start to predict the next number.

• Common multiples

  Highlight the multiples of 3 in yellow and the multiples of 4 in blue. The squares with a yellow and a blue border are shared, which is a quiet way into common multiples.

• Missing numbers

  Hide the numbers, print the empty chart and ask children to fill it in from memory, or give them only the first row and the last column as clues.

• Mystery pattern at home

  Colour a pattern in secret, such as the numbers that end in 3, and ask your child to describe the rule that fits the coloured squares.
