Four operations with decimals

  • Year group: Year 5
  • Term: Summer
  • Topic: Decimals
  • Duration: 4 weeks
  • Keystage: KS2
  • Age Range: 9 to 10 yrs
  • Unit can be taught out of sequence: N
  • Week Range: 1 - 4

In this chapter, pupils convert between fractions and decimals and calculate with decimals.

Building on work from the previous chapter, pupils read, write, order and compare numbers with up to three decimal places. They recognise and use thousandths and relate them to tenths and hundredths, as well as decimal equivalents and measures.

Pupils round decimals with two decimal places to the nearest whole number and to one decimal place. They say, read and write decimal fractions and related tenths, hundredths and thousandths accurately, and read and write decimal numbers as fractions (eg, 0.71 = 71100).

Linked with previous work on addition and subtraction, pupils count using decimals and fractions above and below zero. They mentally add and subtract tenths, as well as one-digit whole numbers and tenths. They practise adding and subtracting decimals, as well as whole numbers with decimals, decimals with different numbers of decimal places and also complements of 1 (eg, 0.83 + 0.17 = 1). Pupils recognise and describe linear number sequences involving fractions and decimals (eg, 3 , 312, 4, 412...) and find the term-to-term rule in words (eg, add 12).

Pupils multiply and divide whole numbers and those with decimals by 10, 100 and 1,000. In doing so, they interpret non-integer answers to division problems and express them in different ways according to the context. Answers are expressed as fractions, as numbers with remainders and as decimals (eg, 98 ÷ 4 = 984 = 24 r2 = 24 12 = 24.5 ≈ 25).

By the end of this chapter, pupils use all four operations to solve length, mass, volume or money problems using decimal notation. They go beyond the measurement and money models of decimals to solve number puzzles involving decimals. As a result of their extensive work on place value in previous topics, pupils check the reasonableness of their answers confidently.

Addition and subtraction of decimals

This worksheet and problem cards will help students deepen their understanding of addition and subtraction of decimals.
By WRMaths

Reasoning - Problem Solving - Number Problems Galore - March 16th

Here are today's questions. There are two problems for KS1 and two for KS2.

In KS1 problem children have to find missing numbers in an addition pyramid and see if they can reason to find a missing number in a different one. They then have to solve a multi-step problem, which initially looks easier than it actually is.

At KS2 children have to be able to adding fractions and decimals together and convert between fraction and decimal. For the second question children have to adding and subtract decimals after converting to the same unit of measure.

Every day in March the White Rose Maths Hub is aiming to put out a question of the day.

Tweet us @WRMathsHub a picture of your children's answers for a chance to win a prize.

adding decimals - 'Boxes' game. (Adding 1 Dp)

This game is like a game I played when I was little. Two players take it in turns to join 2 dots. When the grid becomes fuller you can complete boxes. If this happens you claim the square and get that score. Winner is the one with the highest score at the end.

Theme Park, Maths Enterprise

This is a group of resources I made (I used some ideas from other places, but I made the things myself) in order to use as many Maths related exercises with the final aim of creating their own theme park. Some of the skills covered are:
Shapes, co-ordinates, symmetry, speed, line graphs, pictograms, bar graphs, perimeter, area, percentages, tally, problem solving, survey, money, budget and time.

Enjoy!!

Decimal multiplication and division

Teachers should use this resource to teach a class alongside laminated partitioning boards, mini whiteboards and pens. WALT (We are learning today) - 1 To multiply by a whole number first place decimals and decimals with more than one decimal place. 2 To divide by a whole number first place decimal. 3 To understand how multiplying or dividing decimals by 10 moves figures one place to the left or right. I've found so many useful resources on this site I thought it was time to share one of my resources with others. I hope you find it useful and if you do please leave a review. Thank you.
