# Term 2a (Jan/Feb)

P5 Numeracy – Term 2a (January/February)

Here you will find the topics we have been doing in class and some websites which will help practise these skills at home. Also remember to log-in to Studyladder, where you will also find PODS linked to our focused topics in Numeracy for Term 2a.

Multiplication

You had started to learn your multiplication tables at home before Christmas and that is the main focus for this half term. It is important that you know ALL of your times tables in P5. Start with revising x2,5,10,3 and 4 which you would have learned in P4 also and then progress onto x6,7,8 and 9. If you can, try to go over x11 and x12 as well…if you learn these while learning the other tables, then they won’t seem so scary.

Use the links to these games to help practise those tables at home. There may also be some practical things you could do at home to help you learn your tables…

• Do you have stairs in your house? As you go up the stairs, pick a table and say the answer as you go up each step. E.g. x6 à 6, 12, 18, 24, 30 etc.
• Have you a ball? If it is dry. Go outside and bounce the ball off the ground or wall. Every time you catch the ball say the answer to the table, e.g. x8 à 8, 16, 24, 32, 40 etc.

You will also have a log in for Times Tables Rockstars, so don’t forget to log into this to practice your tables too. It’s a great way to practise. Click on the picture to go straight there and check with your teacher if you're unsure of your login.

Multiplying a number by 10/100

This half-term, we will also be looking at multiplying any number by 10/100. When we are multiplying numbers by 10 we need to move the numbers over one space to the left and place a 0 in the unit’s column. Have a little look at the following videos which will help you understand this a little better. I think the little girl in the video explains it probably better than I can….enjoy! (Just remember we call the ones column units) J

You can also practise by playing these games:

## Multiplying by 10 and 100

In this video we are looking at multiplying whole numbers by 10 and 100. We use a place value slider to show how digits move one column to the left when mult...

We will also be looking at multiplying single digits (units) by a multiple of 10/100 (a number that ends with 1 zero or 2 zeros).

E.g.

60 x 4  - The easiest way to do this is Mrs Boyd’s little helpful trick.

Cover the zero in 60 to get 6. Multiply 6 x 4 which is 24 and then put

the zero back on he end of the number – 240

60 x 4 = 24

7 x 300 – Again, cover the zeros but remember this time there are two.

7 x 3 = 21 and then place the 2 zeros back on the end of the number.

7 x 3 = 2100 or 2,100

## Multiplying by Multiples of 10

Multiply numbers by multiples of 10.

Have a little look at the following games which you can play to help you further. Take your time with this work and you REALLY need to know your tables so if you’re still not sure on some of those, spend some more time practising the ones you’re not sure of. (It could be x7/8/9). Enjoy!

Written Multiplication – Grid and Formal

This half-term we will be learning how to complete written multiplication of TU by U and HTU by U (perhaps moving to ThHTU by U).

We have two methods to learn…grid multiplying and the more formal method. Watch the following videos showing you how to complete the grid method of multiplication.

2D Shape

This half-term, we will also be looking at some lessons on 2D Shape. We start by looking at lines. There are lots of different type of lines. There are horizontal lines, vertical lines and oblique lines. You are also going to learn about parallel and perpendicular lines.

Parallel lines are two (or maybe more), but we’ll stick with two, that never meet. You could extend the lines further in either direction and they still would never meet.

Perpendicular lines are two lines which cross each other and at the point where they cross, they make a right angle (90 degrees). Remember we can make a right angle with our two arms. One going horizontal and one vertical and each arm meeting at the elbow.

## Geometric lines for kids - Geometry for kids

Educational video for kids to learn types of geometric line types, like straight lines (horizontal, perpendicular, vertical) and curved lines (open or closed...

We then move onto looking at various different 2D shapes and their properties. We think about how many sides they have, if they are all the same or different, how many angles the shapes have and whether these are right angles or not. We also think about whether the shapes tessellate or not and look at finding the perimeter of some of the shapes.

Here are a few things to remember:

Perimeter – this is the distance around the outside of the shape. You measure each side and then add them up, easy peasy.

Lines of Symmetry - this is cutting a shape into two equal pieces and if you fold it over through the cut, both pieces would fit exactly together.

## Line Of Symmetry | Mathematics Grade 4 | Periwinkle

Tessellating – this is fitting shapes together with no gaps or overlaps.

## Tessellation | Mathematics Grade 3 | Periwinkle

Shapes that we will look at are: Square, rectangle, triangles (Equilateral, Isosceles and Scalene), Circle, Pentagon and Hexagon. Here are a few videos for you to watch. Why don’t you look for different 2D shapes at home or when you’re out and about? How many different 2D shapes can you find?
