Please listen carefully to this beautiful story written by Dr.Seuss. Once you've listened please have a go at the follow up task linked just after!
This shows how to multiply a 2-digit number by a 1-digit number using the grid method. To multiply a 2 digit by a 2 digit, use the same method, just add another row, so a bit like a X and O grid. Don't forget to multiply the numbers on the outside, to get the numbers on the inside before adding them up.
Have a go at these:
12x3
15x6
18x9
12x4
11x4
17x2
13x11
12x17
16x18
21x11
Column method subtraction including lower digits in the top row.
watch and then on scrap paper have a go at:
56-13
89-12
75-12
198-23
256-21
672-12
62-37
81-39
156-19
This video will show you how to use the column method in Maths for addition when all columns total ten or more and therefore require carrying of digits.
Then on some paper have a go at answering these:
56 +45
23+78
126+23
187+17
298+43
178+145
672+892
1892+451
1234+45
