Place Value

Professor Assessor (about 30 minutes)

• Professor Assessor is really important because it gives your teachers and TAs, as well as yourselves and your parents, the chance to analyse your learning and to track your progress.

• Well done to everyone who completed the assessment I set you last week called ‘Assessment Addition and Subtraction 1’.

• This week, I have set you a Times Tables test, called ‘Times Tables Test 1’.

• Please log in and have a go – you only have one week to complete this!

• You were sent home with your login details in your home learning packs. To access the site, please click on the link: https://www.prof123.co.uk/Start. The school code is: BRN

Mathletics (about 30 minutes)

• Just like Professor Assessor, Mathletics is really important because it gives your teachers and TAs, as well as yourselves and your parents, the chance to analyse your learning and to track your progress.

• Well done to those of you that completed the Fractions work I set last week!

• This week, you have some work on Fractions to do. Please log in and have a go if you haven’t already! Some of you have completed all of the Fractions activities, so I have set you some work on Number and Place Value.

Introduction

• This week, we are going to revise Number and Place Value. • We are going to revise how to:

– count from 0 in multiples of 4, 8, 50 and 100; – recognise the place value of each digit in a three-digit number (h, t, o) – find 10 or 100 more or less than a given number – compare and order numbers up to 1000 – identify, represent and estimate numbers using different representations – read and write numbers up to 1000 in numerals and in words – solve number problems and practical problems involving these ideas.

• Each week, I will also set you a Mental Maths worksheet, (choose a sheet) as well as some revision work on addition, subtraction, multiplication or division, or some problem solving to do!

• I’d also like you to spend some time each week on Professor Assessor and Mathletics. This might be revising topics we have already covered, work on our current topics, or times tables practise. I will set you tasks or assessments each week to complete.

multiplication skills to

answer these questions.

Place value

• We use place value headings like 1, 10, 100, and 1000.

• These help us do sums and see which numbers are bigger than others.

• A number is made of one or more digits.

• The number 6379, for example, is made of the digits 6, 3, 7 and 9.

• 6 thousands, 3 hundreds, 7 tens and 9 ones.

Place value

• Watch this short video to help you revise place value (it’s very funny!), then do the three check activities and the quiz afterwards:

Rounding Numbers

• Rounding to the nearest 10 • To round a number to the nearest 10, look at the

units digit. If the units digit is 5 or more, round up. If the units digit is 4 or less, round down.

• The last digit in 356 is 6. So we round it up to 360. • The last digit of 352 is 2. So we round it down to

350. • 475 ends in a 5. We always round a 5 up. So 475

rounds up to 480.

Rounding Numbers

• Rounding to the nearest 100

• To round a number to the nearest 100, look at the tens digit. If the tens digit is 5 or more, round up. If the tens digit is 4 or less, round down.

• The tens digit in 3281 is 8. So we round it up to 3300.

• The tens digit of 3216 is 1. So we round it down to 3200

Rounding Numbers

• Rounding to the nearest 1000

• To round a number to the nearest 1000, look at the hundreds digit. If the hundreds digit is 5 or more, round up. If the hundreds digit is 4 or less, round down.

• The hundreds digit in 4559 is 5. So we round it up to 5000.

• The hundreds digit of 4295 is 2. So we round it down to 4000.
