I Will Not Drink Juice From A Box!

The Rimu Maths group during their statistical investigation discovered that there are lots of children who bring tetra pak juice boxes to school. This is a problem because these type of containers cannot be recycled. We created these videos to encourage children to try and reduce the number of juice boxes at school.

Coughs and Sneezes Spread Diseases!

The Totara Maths group during their statistical investigation discovered that there are lots of children who come to school feeling unwell causing sickness and disease to spread. We created a public service announcement to encourage children to stop spreading these germs at school. We were inspired by these videos from the 1940's!

Walking to School is Cool

The Kauri Maths group during their statistical investigation discovered that there are lots of children who do not walk to school. We created these music videos to encourage students at Halsey Drive to change their ways and walk to school.

Totara Statistical Investigation

Rimu Statistical Investigation

Kauri Statistical Investigation

In Maths we have been learning about statistics. We first discussed possible problems/issues at school that we could investigate. We then followed the PPDAC cycle to carry out a statistical investigation.

WALT: Define Statistics

Statistics is the gathering of and display of information on graphs such as bar graphs, line graphs, pie graphs and pictographs. We can use this information to answer questions and make changes.

One use of statistics is to gather information and use this information to make a positive change. For example the Wastewise team collected data about how much rubbish went to landfill. The Wastewise team then used this information to teach the children at Halsey Drive School about reducing their littering.

Calculate Percentage Of Whole Numbers

Here are Samarah and Skye sharing how they calculate the percentage of whole numbers.

Converting Improper Fractions

Here is Arav sharing how to convert an improper fraction into a mixed fraction

How Much!!!

Ansh has been carrying out his own maths investigation. He compared the cost of shopping using information provided by our twitter friends Tollgate4A in Eastbourne, England.

All Prices are in New Zealand Dollars.

Exchange rate calculated at 2.26 (£1 = $2.26)

Overall we pay more for these items in Auckland, New Zealand compared to Eastbourne in the UK.

How Many Days in a Millennium?

Ansh has been working on another tricky time question. Check out what he has discovered.

How Many Seconds Are There In A Year?

Ansh our brilliant mathematician has worked out how many seconds there are in a year. Watch his video to find out. 

Rounding and Compensating

Here is Ansh explaining the strategy of rounding and compensating when multiplying.

Measurement

In Maths we are now studying measurement. We will be studying digital and analogue times, timetables, calendars, units of measurement and more. We discussed how measurement plays an important role in all different areas of life. Below are some of our ideas.

Multiplication and Division Strategies

The Totara maths group used the app 'explain everything' to show how to use the strategies of place value partitioning and reversibiilty when multiplying and dividing.

Tangrams

In Geometry today we learned about tangrams. The tangram is a puzzle consisting of seven flat shapes, called tans, which are put together to form shapes. Here is an example of some of the shapes we made today, Do you know what they all are?

Ansh's Rounding and Compensating Strategy

Here is Ansh describing how to use the maths strategy of rounding and compensating.
