Partition 3-digit numbers; place on a line - Teaching Presentation - Year 3

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

• Place 3-digit numbers on a line
• Partition into 1s, 10s 100s

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
Discuss how we mark 2-digit numbers on a line 0–100. Then mark 275 on a line 200–300. Discuss halfway, and where 275 goes. Repeat, marking numbers on a 400–500 line.

Day 2 Teaching
Review the top tips written yesterday. Model how to think about half and quarter to help place 3-digit numbers on a 0–1000 line.

Day 3 Teaching
Play the Nasty Game. Show a place value grid (100s, 10s and 1s). Write different numbers on the grid, discussing their place value.

Day 4 Teaching
Compare and order numbers using the place value grid. Discuss which digit to look at when the hundreds digit is the same. Find 3-digit numbers which fall between two given 3-digit numbers.

Day 5 Teaching
Challenge children to write the largest 3-digit number using digits 0–9 only once each. Repeat for other target numbers.

This teaching is part of Hamilton’s Year 3 Place Value 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.
