- 3. Jill wants to build a wall 4 meters high. When she arrives at the shop, the shop manager said that there were only bricks 1 cm high. How many bricks would she need to build up to 4 meters high? M 4m There are 100 cm in 1 meter so Cm A:_____cm 400 400 100x4=________ cm
- 4. Sam has a bag of flour 53 kg. Jenny has another bag of flour 8490 cg, while Ben has a big bag of flour weighing 1.97 t. How many grams of flour they have altogether? This is a more complicated question and will require at least 4 slides to answer.
- 5. First, let’s take a look at the chart. Sam had 53kg so let’s convert it. When you want to convert a Big unit to a Little unit, the number has to go Up. (BLU) But when you want to convert a Little unit to a Big unit, the number has to go Down (LBD) In this case, we have to convert a small unit to a bigger unit so the number has to go up (BLU) That means Sam has G 5300 (10 G in a Dag & 100 G in a KG) 5300 grams of flour Dag 530 (10 Dag in a Kg) Kg 53 t
- 6. Now, take a look at Jenny’s bag of flour (8490 cg) and this time, we will use LBD (converting a Little unit to a Big unit means the number has to go Down) That means Jenny has 84.9 grams of flour. Cg 8490 cg Dg 849 dg G 84.9 g
- 7. Now let’s take a look at Ben’s big bag of flour but remember, 1 tonne = 1000 kg. Also, we are going to make a Big unit to a Little unit so the number has to go Up (BLU) G 197000 Dag 19700 Kg 1970 T 1.97
- 8. Now that we have got all the answers, we just have to add them up because in the question, it says: “How many grams of flour they have altogether?”
