Counting in 1/2s and 1/4s; finding fractions of amounts - Teaching Presentation - Year 2

This presentation provides three days of teaching that cover the objectives:

• Count on in fraction steps.
• Find 1/2, 1/3, 1/4 and 3/4 of amounts using sharing and number facts

It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards.

Day 1 Teaching
Use folded circles (1/2s) and rectangles (1/4s) as a visual aid for counting in fraction steps. Count on in 1/2s to 10; count on in 1/4s to 5. Each child shows the relevant fractions as they count. Remind children that 2/4 is the same as 1/2. Use a TA to model writing halves and quarters on a 0 to 5 number line.

Day 2 Teaching
Use 12 bananas (real or use an image) as an amount to model sharing into 1/2, 1/4 and then to find 3/4. Look how the fraction tells us what to do with the amount: 3/4. The 4 tells us to share the whole amount between four; the 3 tells us that we want to know what is in three of those groups. Repeat to share 12 and 18 into thirds.

Day 3 Teaching
Show a recipe. Demonstrate how to find half of each of the amounts to make half the number of cakes. Demonstrate how to find 1/3 of amounts. Then demonstrate to find 1/4 by halving and halving again.

This teaching is part of Hamilton’s Year 2 Number, Fractions and Money block. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.
