Choose a pair of numbers e.g. 60 and 16. Explain that the first syllable (or clap) is the same and the second is different. Use the syllable frame and place the first syllable (e.g. ‘six’) on the first clap in the frame. Then say one of the numbers and the child has to decide whether ‘ty’ or ‘teen’ should go on the second clap. If they choose correctly read the number together. Repeat with each pair of numbers (e.g. 13/30; 14/40; 15/50 etc). Don’t forget to vary the order you present the number or the child will learn the pattern.
