Pounamu Pendants

This week for maths we are doing measurement. Using a picture of a pounamu on  a grid  that was 9 by 15 there were 135 squares all together. We had to figure out what the percentage of the grid was a Pendant. First I figured out how many squares of the grid where all pounamu. Some of the squares were Pendant and background so I had to add two squares together, like one square was ¾ background and ¼ Pendant so I added it to a square that had ¼  background and ¾  Pendant  because that made one complete  square of Pendant. Then once we finished finding out how many squares of Pendant we had to find the percentage. To find the percentage multiply the answer by 100, E.G - 65 (Pendant) ÷ 135 = 0.48 x 100 = 48. At first finding the percentage was hard but it got easier the more I tried it. Do you know how to find the percentage of something?

Going to Extraordinary Lengths

This week  in Te Ngahere we have been learning about prime numbers. The purpose of my blog post is to teach people about prime numbers. A prime number is a number that can only be divided by one and itself, e.g - 7, you can only divide seven by one and seven (itself) that means that is is a prime number. For our maths activity we had to find all of the prime numbers to 100. After we found out all of the prime numbers we then had to make a DLO based on how we solved our problem. At first figuring out the prime numbers were easy but as the numbers got bigger finding the prime numbers got a bit harder. This is my DLO. Did you learn anything from my blog post?

Tessellations

In Te Ngahere we have been creating tessellations.
First the teacher gave us some mathematical words related to the
math we were doing. We had to find the meaning behind tesselating,
translation, rotation, reflection and symmetry.  A Tessellation is an
arrangement of one or more shapes that are fitted together without
any gaps. After that we made a shape on our computer that could
be tessellated. After we decided to create a tessellation using quadrilaterals.
The shape that I decided to use looked almost the same as  a Nike Tick,
when I had rotated the shape to line up to the rest of the other shapes
so there were no gaps showing. This is the DLO I have created about
Tessellations with Nevaeh.

Math

WALT - solve multiplication problems by doubling and halving.

This week our class has been learning to use doubling and halving to solve big multiplication problems like
5 x 44 = ___ - double the the 5 and half the 44 = 10 x 22 = 220. This strategy make big multiplication problems
easier to work out. We had to work out lots of hard problems using this strategy, it was very easy for me to use this
strategy after a little while once I had got the hang of it. I did not find this strategy hard to us.

After we had done all the evidence we had to make a DLO to explain step by step  how to use this strategy for
multiplication problems. I find making this DLO hard.
This is my finished DLO

Math Problem solving

In Te Maunga we made flubber for math problem solving,

We used  PVA glue, Borax, Liquid dye and water.

First we had to figure out how many teaspoons where in  ½ cup, one cup and four.

½ cup = 25 tsp

1 cup = 50 tsp

4 cups = 200 tsp

Then we made the flubber, first we put the glue in a Big bowl.

Then we boiled the water and added the Borax

After that we put the water and Borax in to the glue and mixed it.

Then we put food coloring in the mixture and mix more,

We had to put more glue in the mix because it was not working.

We tried to fix it but it did not work.

Math Goals

In Te Maunga we made our Math goals,

first we had to make a new google drawing in our math folder. Then we got our math goals from a sheet that had the example and the name of it, if it look to hard or you didn't understand it you had to put it on your google drawing. You also got your goals from your test, if it was highlighted yellow you had to put it on you google drawing because you had got it wrong. After that we got to decorate it. Our WALT was We Are Learning To identify our learning needs.

Math

4/7/18

This term in Te Maunga we have been doing math problem solving for math. Math problem solving is when you are in groups and you have to work out problems using your times tables and division. This week we did Matariki problem solving.We had to find out how many points all the Matariki stars had all together if they had 5 points and if they had 7 points. The answer for 5 points was 5 x 7 = 35 and the answer for 7 points was 7 x 7 = 49.
