Effective mental strategies come from plenty of practice. Here are four Counting by 25s Money Posters to help your Stage 2 students find a way to mentally add multiples of 25 without the need for pencil and paper or a calculator to help them. There’s a poster for 25 cents, $2.50, $25 and $250. Daily practice counting aloud will help them find their own way to visualise the pattern.
And if you enjoy using those with your class, there is also a set of four Counting by 75s Money Posters too.
