2JW Maths

Autumn 1

We have been using different manipulatives to represent 2 and 3 digit numbers. We have then drawn a pictoral representation of these manipulatives. We have been thinking about the value of each digit in a number.

                                       

Using our knowledge of place value we have partitioned numbers:

We then applied this to partition numbers in different ways. For example:

87

80 + 7

70 + 17

60 + 27

50 + 37

40 + 47

30 + 57 and so on.......

 

We have then used mathematical symbols to compare numbers.

We moved onto looking at addition:

And then subtraction:

 

Autumn 2

We've moved onto looking at multiplication and started by looking at equal groups.

      

We then looked at how we can arrange equal groups in a more organised way by using an array. A array can represent 2 different x calculations.

Can you link this work to your times tables and practise your 2x, 5x and 10x tables at home?

 

This week we have been looking at MONEY. Get some money out at home and see if you can name all of the coins and all of the notes. Get a handful of money. How much do you have altogether? What is the most efficient way of counting the money? Can you count in 2's, 5's or 10's to help you? 

 

We have then applied what we know about money to solve some problems. Have a go at home:

        

 

We have been using what we know about a 100 square to help us solve problems:

 

We revisited our work on subtraction and used it to help us solve word problems. We had to read each problem carefully to work out what calcuation we needed to do.

                

 

We discussed what happens if we use partitioning to subtract a number and we don't have enough ones:

34 - 9 = 

 

 

Spring 1

We have focused on division this week. We have learned how to divide by either sharing into equal groups OR grouping. 

We have then applied this to help us solve problems:

 

We have now learned different ways to work out all 4 calculations. We know that we can get concrete appartaus to help us such as ten sticks and ones. We also know that we can draw images to help. Here is a reminder of some of the ways we can work each calculation out:

  

Multiples of 2, 3, 4, 5 and 10

We have been learning about multiples this week. We have focused on how our multiples link to our times tables knowledge. For example:

Multiples of 2:     2, 4, 6, 8, 10, 12, 14, 16, 18.........

                           1 x 2 = 2

                           2 x 2 = 4

                           3 x 2 = 6

                           4 x 2 = 8...............

Please practise your 2, 3, 4, 5 and 10 times tables at home. Below is a link to a fun website to help with this.

You can also practise your times tables on Maths Shed which uses the same log in as Spelling Shed.
