Year 6 Using formulae worksheets

Use and rearrange simple formulae. Two free editable Word sheets with the same questions: one scaffolded, one not. The answers follow the questions in each file: the same sheet again with every answer in red.

Download the worksheets

Both sheets have exactly the same questions, so the whole class can be taught together. Print on A4 portrait: every page carries the sheet twice, side by side, so you can cut down the middle and two pupils each get a half to stick in their books. Every question sits in its own box and pupils write their answers in their book. The answers follow the questions in each file: the same sheet again with every answer in red. Both open in Word, Google Docs, Pages and LibreOffice, so you can change numbers, delete questions or add your own.

Scaffolded sheet

First page of the scaffolded Using formulae sheet, printed twice side by side

Key words highlighted, a hint under each question, and help charts or number lines. For pupils who are working towards the expected standard.

Not scaffolded sheet

First page of the not scaffolded Using formulae sheet, printed twice side by side

The same questions without the extra support. For pupils working at the expected standard: eight fluency questions first, then the reasoning questions.

Sample questions from this step

These are real questions from the first set of the sheet (two from the fluency page, two from the reasoning page). Open each one to see the answer.

  1. Here is a pattern of squares made from lolly sticks. Complete the table.
    Shapes1234510Sticks4710abc
    a = ____
    b = ____
    c = ____
    Show the answer

    13; 16; 31

  2. A shop prints designs on T-shirts. This formula gives the price in pence: p = 40c + 150 (p is the price in pence and c is the number of colours).
    Price of a design with 4 colours: ____
    Show the answer

    £3.10

  3. Dora makes a square pattern from lolly sticks. 1 square needs 4 sticks. 2 squares need 7 sticks. 3 squares need 10 sticks.
    Amir: You need 14 sticks to make 4 squares. I multiplied the number for 2 squares by 2.
    Is Amir correct? Circle yes or no.
    Circle yes or no.
    Explain. Then write the correct number.
    Correct number of sticks: ____
    Show the answer

    No; No. Squares share sticks, so you cannot just multiply. Each new square needs 3 more sticks, so 4 squares need 3 × 4 + 1 = 13 sticks.; 13

  4. A rule for cooking a chicken is t = 45m + 15, where t is the time in minutes and m is the mass in kilograms.
    a) The time for a 2 kg chicken: ____ minutes
    b) The mass of a chicken that takes 105 minutes: ____ kg
    Show the answer

    105; 2

What is on each sheet

  • Fluency: eight questions that start easy and get harder, with the key skill of the step practised in different ways.
  • Reasoning: questions with pictures, tables and number lines (spot the mistake, true or false and explain, puzzles with one answer, an open-ended task).
  • Answers in the same file: the sheet again with every answer in red, so there is only one file to download.
  • Boba characters give the instructions in speech bubbles. They are decoration only.
