We will identify 1 a fraction of a whole. 1 find CFU Students, sometimes we have to split a whole into smaller parts. In math, we call each part “a fraction of the whole”. Now, we will identify a fraction of a whole. Activate (or provide) Prior Knowledge How would you split a whole toast into 2 parts so that 2 people get the same amount? 12 34 How would you split a whole cookie into 4 parts so that 4 people get the same amount? 12
