2 II. Look at the objects and indicate which one is heavier/longer/has more capacity a. The rack is heavier b. The tub has more capacity c. The palm trees are taller

3 III. Write the correct weight looking at the figures a = 500 gms 100gms 100gms 100gms 100gms 100gms b. + + = 175gms 25 gms 50gms 100gms 5cms +5 cms +5cms + c. 5 cms = 20cms

in kgs and heavier than the glass 600 gms

lighter than the water melon Since it is

4 IV. Match the picture to the correct weight/length 15 meters Since it is measured in meters and longer than the scale 500gms +500gms Since it is measured in kgs and heavier than the glass 600 gms Since it is measured in grams and is lighter than the water melon Since it is measured in centimeters and is shorter than the length of a bus 10 cms +5 cms

5 V. Word Problems a. Reema had a pack of ice-cream of 201ml. If she ate 12ml of ice-cream from the pack, how much ice-cream was left? Solution : Capacity of the ice-cream pack = 201 ml Capacity of ice cream Reema ate = 12 ml Capacity of ice cream left = 201ml 12 ml Since you lent one to your neighbor on the right 2 becomes 1 Since 1 cannot be 0, borrow 1 from 0 becomes becomes 9 since you lent 1 to your neighbor on the right Since 2 cannot be 1, borrow 1 from 1 becomes Ans = 189 ml Important b. A box of cards weighed 220gms. Cards weighing 32 grams were removed from the bag. What was the weight of the box? Solution : Weight of the box of cards = 220 grams Weight of the cards that were removed = 32 grams Weight of the box after the cards were removed 220grams 32 grams

6 Since you lent one to your neighbor on the right, 2 becomes 1 Since 3 cannot be 2, borrow 1 from 2 becomes becomes 11 since you lent 1 to your neighbor on the right Since 2 cannot be 0, borrow 1 from 0 becomes Ans = 188 grams Important c. David bought 216 cms of cloth to stitch shirts.he also bought 132 cms of cloth to stitch his trousers. How much cloth did he buy in all? Solution : Length of cold David bought to stitch shirts = 216 centimeters Length of cloth he bought to stitch trousers = 132 centimeters Total cloth bought by David = 216 centimeters centimeters Ans = 348 centimeters

7 d. A water tanker had 552 litres. 238 litres leaked out of the tanker. How many litres are left in the tanker? Solution : Capacity of water a water tanker can hold = 552 litres Capacity of water that leaked out of the tanker = 238 litres Capacity of water left in the tanker = 552 litres 238 litres Since you lent 1 to your neighbor, 5 becomes Since 8 cannot be 2, borrow 1 from 2 becomes Ans = 314 litres e. A housewife bought 750gms of onions, 1000gms of potatoes and 250 grams of beans from a vegetable shop. How much vegetables d id she buy in all? Write your answer in kgs.
