Maths Friday 2017-18
Welcome to the Year 5 Maths page!
Here you will find a range of activities for the children to do at home to consolidate skills we have been learning in the classroom and to keep you informed about what we've been doing.
We have started looking at place value with numbers up to 7 digits. We ordered some numbers and used greater than and smaller than arrows, finding numbers which would fit between. The children have a sheet with some similar activities for homework this weekend. Please don't worry if they do not have time to complete it straight away - I'm happy to see it whenever it is done!
Well done with the homework everyone.
This week we have gone over multipying by 10 and 100 and dividing by 10 and 100, recognising that multiplying will make the numbers 10 or 100 times larger, whilst dividing will make them smaller. We extended to one place decimals too. We also looked at strategies for doubling and halving numbers, remembering that partitioning numbers helps eg 156 x 2 = 100 + 50 + 6 so 200 + 100 +12 =312 and 156 divided by 2 = 100 + 50 + 6 so 50 + 25 + 3 = 78.
Homework this week goes over one or other of these skills.
We have covered rules for rounding numbers to the nearest 10 and 100 this week. Then we have looked at multiplying 3 digit numbers by a single digit, using either the partitioning method or a grid. We moved on to multiplying with decimals too. The homework sheet is about grid multiplication. Reasoning tasks this week have been about using strategies of trial and error and following instructions step by step to get to an answer.
We have been continuing to multiply HTU by U using a grid and we have looked at dividing by 'chunking' or repeated subtraction. For 78 divide by 6 see the method below.
(10 x 6)
(3 x 6)
How many 6s have subtracted?
10 + 3 sixes have been subtracted.
Record 78 ÷ 6 = 13 so the answer is 13.
46÷3 Remember to approximate first. 46÷3 lies between 30÷3 = 10 and 60÷3 = 20
46÷3 = 15 r 1 46
Now check your answer against your approximation.
The homework sheet is to help use the method which some children found quite challenging.
If you fancy more challenge, how about these?
173÷5 Remember to approximate first. 173÷5 lies between 150÷5 = 30 and 200÷5 = 40
173÷5 = 34 r 3 173
1. 159÷6 4. 235÷4
2. 146÷3 5. 194÷6
Weeks 5 and 6
We have been working on fractions and decimals for the last two weeks, revising and moving on. We have looked at improper fractions, mixed numbers, equivalent fractions and placing fractions on a number line. We looked at values of 2 place decimals and ordered smallest to largest, with 1 and 2 places. The children need to recognise tenths and hundredths so we have been using place value mats to help. There isn't a homework sheet this weekend but any fraction and decimal activities or maths games would help consolidate understanding.
We have been doing data handling this week, looking at the language of probability, creating data and turning it into a bar chart. We looked at bar line graphs and how to answer questions and interpret the data.
We have revised names of 2d shapes and begun to look at properties, such as sides and angles. We have used language like diagonal, horizontal, vertical and parallel to describe lines, regular and irregular to describe shapes and have looked for lines of symmetry. Please encourage the children to play maths games on maths websites to help consolidate their learning. Decision tree classification of triangles sheet for homework.
This week we have continued working on properties of rectangles, squares and triangles. We have also covered how to draw axes and plot co-ordinates. There is a battleships game sheet for you to play for homework this weekend. Remember x comes before y when using co-ordinates!

We have worked on converting measurements mm to cm, cm to m, m to km and the reverse. The children need to remember to multiply by 10, 100 and 1000 or divide by 10, 100 and 1000. We have tried to measure accurately in mm and cm. Any practising on games will help!
We have looked at telling the time on the analogue and digital clock, 24hour times and interpreting timetables. Many children needed quite alot of help with this!
Here is an Alfie test for the holidays!
Spring term 2018
We have completed some real life problems using time, used stop watches to time activities and moved on to properties of number. We have looked at continuing number sequences and recognising the rule needed to complete them. We have used this in reasoning questions too. Homework sheets should be in bags!
This week we have continued to look at number sequences, finding numbers larger, smaller and in between given numbers using larger than/smaller than arrows and finding multiples of numbers.
We have worked on square numbers and found factors of multiples of ten. We also tried to crack some codes finding clues to help us. A times table was written in letters and we had to find a way of working out the value of each letter - once we found the first couple of numbers it became easier!
This week we have looked at negative numbers and temperature differences. We have tried to clarify vocabulary - rises/falls, increases/decreases and how that looks above and below zero degrees. We have plotted temperatures on line graphs and discussed scale and axes. We looked at word problems and one group tried to use a set of clues to discover temperatures in different cities.There is a homework sheet and some squared paper for the children to have another go.
We have looked at column addition and subtraction in different written ways - using a number line to count on and adding columns of hundreds, then tens and units seperately before combining. Some children are using the 'borrowing' method.but if they still find that difficult there are other alternatives to help them find an answer. We started to look at using addition and subtraction in problem solving too. There are homework sheets for consolidation.
