Can you represent a number in different ways?
Think of a number bigger than 20 but smaller than 99. Think how many tens in this number and how many ones.
Can you write it in words?
Can you draw in in base 10 (tens sticks and ones)?
Can you tally it? (Remember to cross the gate every 5)
Can you draw in in a number shape? (numicon)
Can you write it in numerals?
Can you draw it on a bead string?
Can you write a fact about it? (1 more or 1 less)
Can you draw it on a number line?
Can you write a number sentence about it?
Take a look at my example below.
