In lesson seven, students learn a faster way to figure out fractions that equal whole numbers.

They practise applying this analysis up to lesson twelve. In lesson eleven, they review equivalent fractions.

The process in lesson seven is:

Say, ‘Some fractions equal whole numbers. Listen: If a fraction equals 5, the top number is 5 times the bottom number. If a fraction equals 2, the top number is 2 times the bottom number.’
Ask, ‘If a fraction equals 9, the top number is how many times the bottom number?’ and signal. ‘If a fraction equals 30, the top number is how many times the bottom number?’ and signal. ‘If the fraction equals 48, the top number is how many times the bottom number?’ signal and repeat until firm.
Display, ask, ‘All the fractions will equal 4. So, the top number of each fraction is how many times the bottom number?’ and signal.
Point to the /3, ask, ‘What’s the bottom number?’ and signal. ‘The top number is how many times 3?’ and signal. Ask, ‘So, what’s the top number?’ and signal.
Continue the process with the other four fractions.
