Term 4 Week 3: Maths

I was learning to figure out problems including weight and capacity. I'm blogging this because I want to show my maths.

Weight and Capacity

Four  problems to solve.

1. Think what balance scales look like (image a see-saw)

Draw five diagrams of different looking balance scales and put on each side what might be being weighed

A school bus has a 2600 kg carrying capacity,  How many people would it be permitted to carry?   (think about the difference of child and adult)

Child = 30 KGs each

Adult = 70 KGs each

40 Children = 1200 KGs

20 Adults = 1400 KGs

1200 KGs + 1400 KGs = 2600 KGs

2. I can see a selection of containers with a capacity bigger than 1 L but smaller than 2 L.  What might the containers be?

            1.5kgs , 1.1kgs , 1.2kgs , 1.3kgs , 1.4kgs , 1.6kgs , 1.7kgs , 1.8kgs , 1.9kgs ,

because the containers are bpthe filled with a kg and they are meant to be Litre containers.

3. Make three different packages that have a mass of 1 kg.  Compare the size of your packages and discuss why they can be so different but have the same mass.

1 kg of feathers , 1 kg of flour , 1 kg of rice bubbles

1kg of flour is heavier than 1kg of feathers because

They are all the same.
