Real-life questions about length, weight and capacity: cutting ribbon, weighing parcels, filling jugs and changing units. Read the story, work it out and type the answer.
There is 5 L of water in a jug. Lily pours in 1 L more. How much water is in the jug now?
10 mm = 1 cm
100 cm = 1 m
1000 m = 1 km
1000 g = 1 kg
1000 mL = 1 L
Reading a scale: find what each small step is worth.
Change to the same unit before you add, take away or compare.
Scale drawing: multiply each length on the plan by the scale.
Find the measurements in the story and check their units. If they are different, change them to the same unit first, then add, take away, multiply or divide. A bar or a ruler drawing shows which one: a ribbon cut into equal pieces means divide.
Find two numbered marks next to each other and count the small steps between them. If 0 and 1 kg have 5 steps between them, each step is 200 g. Then count on from the last number to the needle or the top of the water.
10 mm = 1 cm, 100 cm = 1 m, 1000 m = 1 km, 1000 g = 1 kg and 1000 mL = 1 L. Going to a smaller unit, multiply: 2.5 m is 250 cm. Going to a bigger unit, divide: 750 g is 0.75 kg.
Ages 5 to 7 add and take away whole centimetres, kilograms and litres and read simple scales. Ages 7 to 9 read jugs marked in 100s and cut lengths into equal pieces. Ages 9 to 11 mix units like metres and centimetres. Ages 11 to 14 work with kilometres, allowances and scale drawings.
