This popular book is great for talking to children about ‘how many in all’ (cardinality) and comparing numbers. After you have read the book to the whole group, have book discussions in small groups. Ask the children questions such as “How many apples did he eat through? Pears? Plums? Strawberries?” See if they can name the total number rather than recount each time. Also notice if they are subitizing or counting one by one. Give the children practice comparing numbers by holding the book open to the pages that are cut out for each fruit. Ask children questions such as, “How many more pears did he eat than apples? How many more oranges than strawberries? How many more oranges than apples?”
Compare the number of pieces of fruit the caterpillar ate through using the language more than and less than. Compare how many more or how many less.
Notice if children are able to subitize the pieces of fruit in the book or have to count them one by one.
