This was our maths problem we did today.

From Auckland to Waitangi is 229 kilometres. We left Auckland at 9.39 am and arrived at Waitangi at 3.31 pm. Remember we also made three stops before we arrived at Waitangi.

Today's maths work was challenging and hard.

 This is one question I came across "What is your estimate for the average speed the bus was travelling?" My answer was 75-85 kph because we mostly travelled on a motor way. The maths problem was very challenging.

Today during maths my maths group and I did a maths problem. The maths problem we did was down below

I did place value partitioning to solve my answer.

Marilyn needs to fertilise her front lawn. It measures 20 metres by 35 metres. Each bag of the fertiliser that she plans to use covers approximately 200m2. How many bags should she buy?

Remember: length X width

1.

20 x 30 = 600

20 x 5 = 100

600 + 100 = 700

20 x 35 = 700

2.

700 ÷  2 = 350

700 ÷ 200 = 3.5

3.

She should buy 4 bags and use half of it and use the other half when she does her lawn again

Today in my class my maths group and I were working on the same question and one of them were

On Saturday we will have a fundraiser car wash for our camp. To save water, for each van we will use only 0.75 litres of water. For a small car like Miss Elia’s car we will use 0.5 litres of water.  How much water do we need to wash 5 vans? How much water do we need to wash 5 cars like Miss Elia’s car?

This is how I worked it out

1. 0.70 x 5 = 3.5

           0.05 x 5 = 0.25

           3.0

          0.20 + 0.50 = 0.70

          0.05 + 0.00 = 0.05

         3.0 + 0.70 + 0.05 = 3.75

        2.  0.50 x 5 = 2.50

Tom and Katie went for a five kilometre run. Tom took 40.23 minutes to complete the run while Katie took 40.92 minutes.

Who was faster and by how many minutes?

Cheryl had 3.5 litres of water to water her plant. Each plant needs 0.5 litres. How many plants can Cheryl water?

Sione ran 0.45 kilometres more on Friday than Saturday. On Saturday he ran 11.25 km. How many kilometres did Sione run on Friday?

The problems above are what my group and I did for maths this morning. The hardest one for me would be the last question. 

For Question 3 this is how I worked it out I worked it out by doing 40 + 20 = 60 and 5 + 5 = 10 so it is 11.70 or 11.7

Today during maths our teacher gave us 16 questions to answer. the first 10 were apart of our maintenance and the next 6 where word problems. The hardest word problem was problem 5. Problem 5 was

Today we had our maths session with Mrs. Raj. Our problem was There are 240 students in a school. 1/5 of them walk to school, 1/3 of them travel by bus, 1/10 of them bike down to school and the rest of them travel to school by car. I learnt some new strategy's I can use to solve problems.
