# Maths

March 2020

We began by  learning about length and perimeter, converting cm into mm, and also cm into m and cm.  Remember : there are 10mm in 1 cm.  There are 100cm in 1m.  The children used this information to measure the perimeter of a 2D shape.  The perimeter = the length around the outside of a shape.

After length and perimeter we moved on to fractions.  The children have learnt the difference between a 'non-unit fraction' and a 'unit fraction' and have been revising the terms 'numerator' and 'denominator'.  They also practised making 1 whole.  We are now moving away from focusing on halves, thirds and quarters to counting in tenths.  Please encourage the children to practise using fractions at home, for example when cutting up food.  What fraction of the pizza have you eaten?  What fraction is left?  How many slices of pizza are there in the whole pizza?  How can we express this as a fraction? e.g. 1 whole = 8/8.

05.02.20 - Continuing our topic on 'money' we have been working at converting pounds to pence and mentally adding amounts of money, ensuring we count the whole pounds first and then the pence.  The children have really improved in their recognition of coins and counting on different amounts of money eg counting on 10ps and 20ps.  We practised counting forwards and backwards in 10, starting at different multiples of 10.

14.01.20 - We began the term by revising how to multiply a 2 digit number by a 1 digit number.  We used the written column method to help us with this. It is very important that the children continue to practise recalling their 2, 3, 4, 5, 8 and 10 times tables at home whenever possible, as this really supports their work at school (there are lots of online times tables games to make this fun!).  We then moved on to dividing, including dividing with a remainder.  We found using equipment such as Base 10 and lolly sticks (or rods) helped us with our understanding of division.

21.01.20 - We have been practising dividing using the 'bus-stop method' (short division), including dividing with remainders, before moving on to 'scaling' numbers.  We changed recipes to increase the quantities produced e.g. by doubling/halving the ingredients.

29.01.20 - This week we have begun our topic on money.  The children have been counting amounts of money, using plastic money to support their learning.  We are also practising converting pounds into pence e.g. 345p = £3.45. Where possible, please give children the opportunity to use/handle money at home.  Give them 5 coins/notes and ask them to calculate the total amount.  Allow them to count the change when you go shopping.

## September 2019 Place Value

This term we have begun by consolidating the children's knowledge of 2 digit numbers with numbers up to 1,000.  The children have built 3 digit numbers with diens blocks, compared amounts and found 10,100 and 1000 more than a given number.  To link with our Roman topic the children have had fun learning the value of each Roman Numeral.  Ask them to show you the Roman numerals for their age or even yours!
