MATHS WORKSHEETS WEEK TWO
MULTIPLICATIONS :
there are different ways of reading 6 x 8
-multiply 6 by 8
8 sixes
6 eights
8 multiplied by 6
Do the same for :
4 x 3 --------------------------------------------------------------------------------------9 x 7 --------------------------------------------------------------------------------------5 x 2 --------------------------------------------------------------------------------------Mental strategies for multiplications
3 x 46
( change 46 deal with it as if it was 40 )
( 3 x 40 is easier to make mentally =120 )
( now take the 6 left behind and multiply it to 3 =18)
( 120 +18=138 )
Follow the same strategy and find the result:
..2 x 52
( change-------deal with it as if it was--------)
( ----x ------- =----------)
( now take the ------left behind, multiply it to ---=-----)
( ---- + -----= -----)
..8 x 34
( change--------deal with it as if it was --------)
( ---- x -------= --------)
( now take the ------left behind, multiply it to----=----)
( ---- + ---- = --------)
PLEASE make sure you learn your 6-7-8 and 9 TIMES tables
6 x 1 =---
7 x 1 =---
8 x 1 =---
9 x 1 =--
6 x 2 =---
7 x 2 = ---
8 x 2 =---

8 x 10=--
9 x 10=--
Here is ANOTHER mental strategy for multiplications
3x 27
27 = 20 + 7
Multiply EACH OF 20 AND 7 BY 3
3 X 20 = 60
3 X 7 = 21
Add the results 60 + 21 = 81
Follow the same steps to find the results of these multiplications :
..5 x 41
-------------------------------------------------------------------------
..4 x 32
-------------------------------------------------------------------------
..2 x 78
-------------------------------------------------------------------------
..4 x 45
-------------------------------------------------------------------------
3 x 58
------------------------------------------------------------------------
NUMBER STORY
..Carla prepared 2 trays of cheese toasts: there are 3 toasts in each tray
to know the total number of toasts 2 x 3 = 6 ( he prepared 6 toasts )
Now read Bill the Baker s story:
..Bill the baker baked 3 trays of cupcakes: in each tray there are 8
cupcakes. How many cupcakes did he bake ? ------- x ------- = -----..He was hungry, so he ate ONE cupcake ! How many are left in the
trays?------- - --------- = -------..His wife came in, asked him to give her 5 cupcakes for her friends : how
many cupcakes are left now ? ---- - ------- = -----..Each piece of cupcake costs 2 p He sold the pieces left to his clients:
How much money did he get ? ------ x ------ = -----
ADDITIONS
835 + 28
first take 30 add it to 20 ( instead of 35 and 28 )
So we have 30 +20 =
50
Now take
13
5+8 =
-----------50 + 13=
63
Last step add 63 to 800 = 863
835 + 28=863
Follow this same strategy and find the result MENTALLY !
1-
465 + 63
------- + --------- =
----
+ -------
-------
= ---------------------------
--------+-------- = ---------------Last step add ---------- to -------- = -------------465 + 63 = -------------
2-
697 + 87
------- + -------- = -------------- + -------- = --------------------------------- + ----- = ------------Last step add ------- to ---------= ----------------
697 + 87 = ----------3-
482 + 15
---------- + -------- = ------------- + ------ = -------------------------------- + ------ = ------------Last step add ------ to -------= -------------- 482+15=----------
