Equivalent Fractions Grade: 3rd to 5th Create equivalent fractions by dividing and shading squares or circles, and match each fraction to its location on the number line. Instructions Modes Along the top, choose Square or Circle. How to Use Use the sliders to increase or decrease the number of columns and rows for Squares or the number of sectors for Circles. Once the shape is divided as you want it, click on the sections to color them. Make the green and blue fractions equivalent to the red fraction.

Click on the Check buttons to see if your fractions match. Note that all fractions must use a different denominator. You will get a message that says, "Use a different denominator," if you make an equivalent fraction that does not use a different denominator. Equivalent Fractions will automatically be added to the table.

To delete a row, use the Trash Can icon in the table. To erase all recordings, use the Reset Table button. Use the New Fraction button to generate a new red fraction.Fraction walls are a great way to teach about fractions and in particular equivalent fractions.

Equivalent fractions - Fractions - Pre-Algebra - Khan Academy

In a fraction wall each row or layer of the wall represents one whole number. The layers are divided into a number of bricks and hence each brick represents a fraction whose denominator is equal to the number of bricks in that layer.

Each brick can be turned on or off by clicking it. This wall also allows the display of decimal and percentage values.

To the right of the wall are boxes which can be hidden, the value of each box is fraction of the wall that has been turned on. When you launch this interactive teaching program the initial wall is a mixed one showing 3 distinct fraction families. Change the wall by using the mode control. The others split the wall along 2s, 3s or 5s. Use the display type control to display decimals rounded to 2dppercentages rounded to 1dpfractions or none.

Normally when you click a brick to turn it on or off, only that brick is affected. However if you turn on the equivalent fraction function by clicking the 'Eq' toggle button. Now when a brick is clicked the other layers will turn on bricks if they can match an equivalent fraction. Note, this is not always possible, in fact if you select the primes wall it is never possible to show an equivalent fraction.

In this case all the other layers have bricks turned off. Also known as 'the lowest common multiple' or 'smallest common multiple' is crucial when adding, subtracting or comparing fractions. This button will calculate the LCM based on the rows that have active bricks. Pressing the LCM button will create a new wall that contains the originally selected fraction but also a new layer with the number of divisions equalling the least common multiple of the denominators of the other rows.

Sounds complicated, but it really just means that it is always possible to create an equivalent fraction in the LCM row from the other rows. To show or hide the advanced section click the advanced toggle button. When the advance controls are on, each layer of the wall has a dedicated slider, move this to change the number the number of bricks in that layer.

Closely related to this activity is the percentage fraction and decimals gridwhich can be used to display a square or circle fraction representation. Other activities that can be used to teach fractions are the clock activity which uses the clock face to show the fraction of minutes passed in an hour. The number explorer activity can show the fraction resulting from division of a number.By how much?

For example, these fractions are exactly the same, but because the larger shape is split into a different number of segments in each case, the fraction is expressed in a different way:.

Children first learn about halving and quartering a shape in Key Stage 1. In Year 3 they are introduced to the concept of equivalencewhere they are shown different shapes like the ones above and asked to write them as fractions.

Children in Year 4 also start learning about decimals and need to know that 0. This can be demonstrated with the use of some blank hundred squares : In Year 5children are expected to find equivalent fractions without the use of diagrams. In Year 5, children would also need to order a set of fractions that had different denominators. For example:. One way of doing this would be to change all the denominators so that they were the same. This would mean multiplying the numerator and the denominator by the same number.

In Year 6children need to use their knowledge of equivalent fractions to simplify fractions. Simplifying a fraction means finding an equivalent fraction where the numbers are reduced as much as possible. Start your trial for FREE today!
