- Whiteboards and pens
- Fractions, decimals and picture fractions
- Fraction bingo
- Ask each child within a pair to write a fraction or decimal in tenths on their whiteboard. Their partner should then say the fraction or decimal and convert it into the opposite, so 1/10 would become 0.1 and vice versa.
- Repeat this activity using fractions or decimals in the thousandths.
Teaching point: Remind children of the value of each column with a number such as 234.67 – although there are six tenths and seven hundredths, we would write 67/100. If necessary, break that down one stage further by explaining the process for adding the 6/10 and 7/100 by converting 6/10 into 60/100 as only fractions with the same denominator can be added and subtracted.
- Now give out the various fractions, decimals and pictures in all their forms and ask the children to compare theirs with others until they form a ‘family’ of three.
- Review some of the families and check everyone has joined up correctly. Discuss percentages and how a percentage is ‘number of parts per hundred’. Ask children who have fractions or decimals which are hundredths to say the equivalent percentage.
- Now play a game of fraction bingo. Give out the bingo cards (based on the fractions you have been using in the earlier part of the session. Explain to the children that you will allow equivalent fractions to be crossed of for this game – so if a child has 0.1 and you say 10%, they could cross off their equivalent decimal fraction.
- Before the game begins, let the children work out what the equivalent fraction, decimal or percentage is for their bingo cards. Keep the game quite relaxed – explain it’s ok for a child to clarify that they have the correct equivalent if they’re not sure!
Make a fraction/decimal/percentage loop card game – each child holds a card which contains two different fractions, decimals or percentages. The game begins when the starter calls out their fraction, decimal or percentage and all other children look to see if they have an equivalent. They say this equivalent, and then say their second fraction, decimal or percentage. Everyone checks again and so on until everyone has had a turn and the game returns to the starter.
Curriculum Areas covered:
(Y5)Pupils should be taught to:
- identify, name and write equivalent fractions of a given fraction, represented visually, including tenths and hundredths
- read and write decimal numbers as fractions [for example, 0.71 = 100 71 ]
- recognise and use thousandths and relate them to tenths, hundredths and decimal equivalents
- recognise the per cent symbol (%) and understand that per cent relates to ‘number of parts per hundred’, and write percentages as a fraction with denominator 100, and as a decimal
