Maths Strategy (working it out )

1. In a survey 198 households had no internet and 38 did. How many households were in the survey?

198-28=?

or 23+?=198

A: 38+2= 40+60= 100+98= 160

add the bold ones not the non bold!!

2. There were 224 students at St Martins school. 78 walked to school and the rest walked. How many walked?

224-78=?

or 78+?=224

78+2= 80+20= 100+100= 200+24=146

3. There were 5 paddocks and each had 42 sheep in them? How many sheep were there altogether?

42X5= 210

5X40=200

5X2=10

200+10= 210

4.Sione shared out his cards with his friends. He had 55 cards and shared the between 5 friends. How many did each friend get :

5x55=11

5x10=50

5x1=5   you add the two number in the MIDDLE!

10+1=11

5. ⅘ of the class are going swimming and the rest  are on detention for forgetting their togs, (this is 7 students) How many are in the class.

4/5 of 7=?

A: -there are 5 boxes and in each boxes there are 7 then add it

7x5=35

My Math Strategy ( by working it out MYSELF )

 Mineus. There were 225 people at the movies than 8 had to leave. How many were left?

225-8=?
- 8+?=225
A: 225-8=217 -  8+217=225


( using reeves and jump! ) 8______+92___________+100_______________+25____225   
                                                                       100                          200
92+
100+
25= 217                        
                        

                                                                                              

Fraction. John has a pizza he has cut into 16 pieces? He eats some then leaves 3/4 of the pizza for the rest of the family How many slices did he eat and how many are left for the family?

= 4,  4 times 4

= 16 so john has eaten 4 pizza’s and left 4 more for the family...

Multiplication.  Tessa has bought 40 mini chocolate bars to put in goodie bags at her party. She has 8 goodie bags. How many does she need to put in each?

= 5 because 5 times 8 = 40 

and she puts 5 mini chocolate bars in each GOODIE bag....

Addition. Trevor has to drive 422 km’s. He looks at his odometer and sees he has gone 289 kms. How much further has he got to go?

422 - ? = 289       289 - ? = 422     

289 + 1 = 290    290 + 10 = 300   300 +122 = 422

122 + 10 + 1 = 133

(using number line)

Math Strategy

1: John has a pizza he has cut into 16 pieces? He eats some then leaves ¾ of the pizza for the rest of the family How many slices did he eat and how many are left for the family?
