Number Framework Stage 3 and 4
Little whiteboards or paper
Allow students multiple opportunities to practise bundling ten to twenty objects into groups of ten and connecting the bundles to symbols and words so that they eventually understand that one ten and ten ones are the same.
Using materials
Problem: Gary has fifteen lollipops. Get me that many lollipops (ice-block sticks). [Allow the students to count out fifteen loose sticks.] Gary’s job at the lollipop shop is to pack ten lollipops together. Can you put ten lollipops together? How many loose lollipops has Gary got left over?
Look for students who have to count one, two, three, four, five and those who know instantly that there are five left over.
Examples: Repeat for numbers from ten to nineteen.
Problem: Shada has this many lollipops [write and point to 17 on the board or in the modelling book without reading aloud]. If she packs ten lollipops in a bag, how many loose lollipops will Shada have left over?
Look for students who have to count one, two, three, four, five, six, seven and those who know instantly that there are seven left over.
Examples: Repeat for numbers from ten to nineteen.
Problem: Caitlin has this many lollipops [draw or model one bundle of ten and four loose sticks on the board or in the modelling book]. Write in symbols and words how many lollipops Caitlin has.
Look for the students who are making the connection between the model, the word, and the symbol.
Examples: Repeat for numbers from ten to nineteen.
Using imaging
Make sixteen as a bundle of ten and six loose ones, then cover with a tea-towel or place in a lolly jar. I have sixteen lollipops in my lolly jar that I have packed into bags of ten. Write down how many loose lollipops there are in my lolly jar.
Look for the students who write six instantly, as a word or a symbol, or who need to count from one or from ten.
If necessary, fold back to “Using materials” by writing “sixteen” or “16” on the board or letting the students see the model of sixteen you have made.
Examples: Repeat for numbers from ten to nineteen.
