WEIGHT

We use grams and kilograms to weigh objects

1 kilogram = 1000 grams 1 kg = 1000g

So….. ½ kg = 500g ¼ kg = 250g

= ½ kg 500g

= ¼ kg 250g

This orange weighs 60 g. 5 pears weigh 700 g This bag of chips weighs 350g These 3 boxes weigh 8 kg 100g

The money box is heavier than the bag. Which is heavier? Full of paper money Full of coins The money box is heavier than the bag.

Choose the heavier 950g of grapes 1 kg of bananas

The heaviest is……. ½kg 750g 1kg

Choose the lighter 1 kg 300 g 1 ½ kg of vegetables 1kg 500g

The point seperates the grams from the kilograms 1kg 135g 2kg 160g 1kg 405g 7kg 300g 1kg 185g 7kg 320g 6kg 850g 1.135kg 2.160kg 1.405kg 7.300kg 1.185kg 7.320kg 6.850kg

Examples How many 200 g will balance: 600g = 200g, 200g, 200g 3 1 kg = 200g, 200g, 200g, 200g, 200g 5 1 kg 5 + 1 kg 400 g 400g 200g, 200g 2 7

How many 100g weights will balance: 2 300 g = 3 ½ kg = 500g = 5 1 ½ kg = 1 kg 500g = 10 + 5 = 15 500g = 5 1 kg 200g = 10 + 2 = 12 2 kg = 2000g = 20

Here are some weights 50g, 100g, 200g, 500g Which of these weights would you use to balance: 1) 150g = 2) 350g = 3) 900g = 4) 1 kg = 5) ½ kg = 100g 50 g 200g 100g 50g 500g 200g 200g 500g 500g 500g

Which 3 of these weights would you use to balance: Here are some weights: 50g, 100g, 200g, 500g, 1kg Which 3 of these weights would you use to balance: 1) 800g = 2) 1½ kg = 3) 1kg 50g = 4) 300g = 5) 900g = 6) 2kg 500g = 7) 3kg = 8) 2 kg = 500g, 200g, 100g 500g, 500g, 500g 500g, 500g, 50g 100g, 100g, 100g 500g, 200g, 200g. 1kg, 1kg, 500g 1kg, 1kg, 1kg 1kg, 500g, 500g

Rick weighs 29kg 370g Ann weighs 35kg 150g Helen weighs 43kg 200g Rick 1. Who is the lightest? 2. Who is the heaviest? 3. How much heavier is Helen than Ann? 4. What is the total weight of Rick and Ann? Rick Helen 43kg 200g - 35kg 150g 8kg 50g 29kg 370g+ 35kg 150g 64kg 520g
