Hundreds tens and ones place value grid. This grid is split into two rows to encourage children to use different resources to think about the difference between eg the number of tens and the value of the tens column. I have used it and encouraged children to think about which resources they would put in each row to best represent the questions that are being asked (for example, the first row asks 'What is it worth?' and I have encouraged children to use base 10 as this shows the value. The second row asks 'How many are there?' and I have encouraged children to draw blank counters or use cubes to represent the digit in that column).
This is best if printed in A3 and then laminated for durability.
