Term 4, Week 6 - Area
Year 5 have been looking at area in Mathematics this week.
We used the formula Area= length x width to find the area of a rectangle or a square. We also used the same formula to find the area of a triangle and then divided our answer by two. For example:

Term 4, Week 5 - Data
This week, students from 5D watched cars driving on Darcy Road and recorded the different colours. We then constructed a column graph to display our results.
Term 4, Week 4 - Mass
We looked at 'net mass' and 'gross mass' and how they are different. Can you answer the question below?
Next time you go food shopping with an adult, have a look at the packaging and see if you can find the words 'net mass'.

Problem:
You have been looking at buying a new DVD player. The same DVD player is available to purchase online and in store. It costs $150.00 at both suppliers.
In the sales, the store offers a straight discount of 60% off the retail price. The online store offers a discount of 20%, followed by a further reduction of 40% on the marked sale price.
Are these discounts the same?
If not, which is the better deal?

Term 3, Week 5 - Position
Activity:
Using a street directory or Google maps, give directions to a family member from one location to another. Give them the starting point, however, don't give them the final location. Remember to include compass directions and distance. For example, if I were starting at the red pin point, I would give these instructions:
Note: I am estimating 1cm = 1km.
Travel north-west along Wentworth Ave for 4.5km.
Turn south-west and travel along A28 for 3km.
At the intersection of Dunmore St and A28, turn south-west and continue along Dunmore St for 4km.
At the intersection of Emert St and Dunmore St, turn south-west and walk for approximately 1km.
What do you see on your right-hand side?

Term 2, Week 4 - Chance
We conducted an experiment in Maths. In pairs, we tossed 3 coins and recorded the outcome. There are 8 different ways that the coins could land. Theoretical probability is what we expect to happen, but in real life, events don't always occur that way. If we toss the 3 coins twenty-four times, the theoretical probability of landing on Heads, Heads, Heads was one eighth of 24 which is 3 times.
"We tossed the coins 24 times and HHH appeared 5 times. It was not the same as the theoretical probability."

"We got HHH four times. It was not the same as the theoretical probability."
