D2: 3/5 = 15/25

Equivalent Fractions Wall

Instructions: Drag the fraction from the left hand side of the fraction wall. See pictures on the left.

D3: Fraction Wall: equivalent fraction diagram with a variety of fractions.

Equivalent Fraction lines

D4: Identify three fractions on a number line (0 to 1)
D5: A number line (0 to 1) split up in to two random fractions, eg 5ths and 20ths.

Lowest common multiple and highest common factor

D6: The lowest common multiple of two numbers, eg 6 and 9
Two options: Click 1 or 2. Option 1 is slightly easier than option 2.
D7: Find the highest common factor of two numbers, eg 36 and 27
D8: Cancel fractions to their simplest form
D9: Find the unknown numerator or denominator

Calculate fractions of amounts

D31: Fractions of amounts in a table and on a fraction diagram
To change the fraction and/or amount click on the fraction buttons.

D10: What is one tenth of 100, 30, 500...
D11: 3/10 of 50, 20, 100...
D12: 4/5 of 50, 35, 100...
D13: 1/5 of 35, 2/3 of 51

D14: Fractions of amounts eg 1/2 of 120, 1/5 of 125
Calculate fractions of amounts. match up the answer with the question.

D15: 3/5 of 17, 2/3 of 25

D32: Percentages of amounts in a table
1%, 2%, 5%, 10%, 20%, 25%, 40%, 50%, 75%, 90% and 100%
Work out mentally or with a calculator.

Use mental methods to calculate percentages

D16: Percentage of money (10%, 15%, 25%, 50% and 75%)
D17: Percentage of money (multiples of 10% and whole number percentages less than 10%)

Use a calculator to calculate percentages

D18: Percentage of money eg 23% of £345

Use mental methods to calculate percentages

D19: Percentage of money (multiples of 5%)

Estimate percentages

D20: Estimate the percentage of a line that is shaded.

D21: Interpret pie charts: estimate the size of each slice.

D22: Estimate percentages and amounts from pie charts.

Calculate percentages of amounts using a calculator

D23: Calculate percentages of a total, a pie chart is shown.

eg 250 people represents 31%
250 ÷ 31represents 1%
250 ÷ 31 x 100 represents 100%

D24: Use a unitary method to calculate amounts, a pie chart is shown.

 

D25: Fractions, decimals and percentages less than or greater than 1/2, 1/4 or 3/4

eg 9:36 = 1:4
eg 12:32 = ? : 8

D26: Simplify a two-part ratio to an equivalent ratio by cancelling.
D27: Simplify a two-part ratio to an equivalent ratio by cancelling. Fill in the missing numbers.

D28: Fill in the missing numbers on a number line.

The ratio can be shown


The proportion can be shown : fractions and percentages

D29: Ratio and proportion generator

Generate different numbers of red squares and blue circles. The ratio of red to blue can be changed. The squares and circles can be scattered randomly or put neatly into rows. Use this resource to illustrate how ratio and proportion works.

The buttons from the left: 1. Generate the shapes in random positions. 2. Place the shapes in rows. 3. Show/hide the number generator panel. 4. Show/hide the ratio. 5. Show/hide the fraction. 6. Show/hide the percentage. 7. Generate a random number of squares and circles. The slider determines the number of groups of each shape.	These sliders determine the ratio of red squares to blue circles.

D30: A flexible whiteboard resource which generates 13 different sets of fractions, decimals or percentages.
There are 13 options:
Select the type of fractions to be generated by clicking on the numbered buttons at the top.

The colour of the tiles can be changed. Select one of 8 colours then click on a tile.

The fractions can be grouped by dragging them about.

The fractions can be discarded by dragging them to the bin.

Children can use the resource to match pairs or group them in threes:
eg 27/100 and 0.73 make 1.
eg 40% of 60 = 24

A clock starts when a set of numbers has been generated. The clock can be hidden or shown (click the green clock button). It can be stopped by clicking the 'stop the clock' button!
The clock can be used to see who can group the fractions in the quickest time.
