Compare and use 3-place decimals - Teaching Presentation - Year 5

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

• Compare and use decimals with 3-places, showing understanding

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
Write on the board 4.378. Ask children what each digit represents. Say both the fraction and the decimal: three tenths; zero point three. Use number cards 0–9 to play decimal number bingo to subtract the value of a digit from a 4-digit number with three decimal places. Show cans/jars with masses in grams. Convert the masses into kg. What does each digit after the decimal point represent? Show a 100g weight: Is this 0.001kg, 0.01kg or 0.1kg? Repeat for a 1g and a 10g weight. Convert millilitres to litres and kilometres to metres.

Day 2 Teaching
Write on the board ☐.☐☐☐ > ☐.☐☐☐. Use 0–9 cards. Take one. Where should we put this card to ensure that the sentence is true? Repeat until each box has a card. Children write a number in between on their whiteboards. Repeat with ☐.☐☐☐ < ☐.☐☐☐. Write numbers: 5.289, 5.974, 5.278 and 5.419. Children order the numbers on their whiteboards. Think of one number between each neighbouring pair of numbers: one with one decimal place, one with two decimal places and one with three decimal places.

This teaching is part of Hamilton’s Year 5 Decimals, Percentages, Fractions 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.
