Received from Covenant Christian School In Stockport: Our older children have begun a topic on converting between fractions, decimals and percentages.
One of the key parts of teaching this subject is that children have a clear understanding that fractions, decimals and percentages work around a base 100. Having the blank 100 square mat that the children could work on in groups was a brilliant resource. The squares were large enough to fit multi-link cubes which the children used to fill every square. They then had to fill in a table showing the total number of each cube, the fraction for each colour and then the percentage.
The following lesson, we used the mat to do quick warms up by colouring in sections and finding out what percentage the children coloured in. This was then linked to place value and writing a percentage as a decimal. The children did some quick warms up on the A4 mats which were transferred easily to our working wall. The children all said by the end of the activity that they clearly understood what percentage meant and could demonstrate their understanding with ease.
This flexible resource meant I (the teacher) did not have to print large numbers of blank 100 squares that the children (as any teacher will know) would spend half the lesson just colouring in. As a whiteboard, the children could make notes directly onto the board together and easily correct any mistakes as their understanding was developing. It was engaging and the children were excited to take part.
The activity was quick and got straight to the heart of the maths.
Being a large board, the children could easily work together in groups either on the table or on the floor, promoting discussion of ideas and helping them to build on each other’s learning. A great resource for an often very daunting topic!
