This week we learnt about adding fractions with a whole number.

Adding fractions with a whole number is by turnign the number into a fraction. For example, if the question was 2/4 of 37 then you would need to turn the 37 into a fraction like 37/1. When turning it into a fraction you need to put the one as the denominator because when you times the question it doesn’t change to bottom denominator but instead changes the numerator.

I found this activity interesting as I learnt a new skill to use in the future.

LI: To create diagram about the top 6 rivers in Auckland

Our math group create a diagram which shows the top six rivers Auckland from smallest to largest. We used our collaborative skills to find out the data of each river. Using our knowledge we put these rivers in this order Whau, Pohui, Tamaki, Waitakere, Hoteo, Wairoa. We used our knowledge to come to the conclusion on what river is the longest out of the 6 rivers in Auckland, which is… 

I found this activity interesting because this shows the diffence between these rivers

LI: To design and make a paper plane that will fly the furthest.

Our team challenge was to create paper airplanes and to see how far it went.  We analysed our data of the paper air planes we flew. The planes we designed were the paper plane 3000, F-14 Tomcat, F-15, Normal paper plane and range flying plane Our group designed multiple planes to verify which of the planes flew the best. The plane that went the furthest was the F-14 Tomcat. Lastly we versed group by group and measured the flight distance accurately. 

I found this task interesting because our planes went far meaning it would be harder to measure.

For maths we made two DLO’s that show what the area is and what shapes are. For example the amount of space a 2D or flat figure takes up or covers. The formula to find the area of a triangle is A=bh (base x height ➗2)

The amount of space a 2D or flat figure takes up or covers. The formula to find the area of a rectangle is A=LxW (Area = length x width).

The distance around a circle. Pi (3.14approx) – the ratio of a circle’s circumference to its diameter. Same for all circles the area of a circle is A=πr² (Area = pi x radius squared eg 9×9)

Some of the shapes are pyramid, triangular prism, Cylinder, Cube, Rectangular prism, spare, cone, Pentagonal prism.

All three of us had to think really hard to get all this information about the 2D and the 3D shapes.

Kahu and I made a DLO talking about how to solve a question. For example 4/5 of 50 = 40.

The first step to solve the question is to write a fraction. An example is 3/7 of 49 that is the number being divided. Next divide the number being divided by the denominator( The number below the line). Once you divid the denominator. You have to multiply the numerator (The number above the line) and once you get the number from dividing that’s your answer. The answer to 3/7 of 49 = 21.
