Additon and Subtraction

Addition and Subraction can be solved by using two strategies: counting on/back, rounding and compensating.

Counting on is adding forward using fingers, when the number added is under ten. Counting back is subtracting using fingers when the number subtracted is under ten.

Rounding and Compensating is rounding the added or subtracted number to the nearest tidy numer, then compensating for the rounding. Compensating is done by splitting the new number into the old number and the leftover.

Counting on/back and rounding and compensating are easy strategies to use for addition and subtraction, when the numbers get too big be solved with basic facts.

SSR Selfie - The Colossal of book Colour

 I readed 18 papge about the Colossal of book Colour.

It was about the difference between the colours. The way we see and interpret colour is critical to understanding the world. Colours can carry meaning that we never consider. Objects that are identical in size, shape and texture can look very different if they are differently coloured.

I enjoyed reading this book because I like to learn about colours.

Basic Facts Boxes

I completed a Speed Demon Challenge in Subtraction up to 20. I got all the answers correct and I finished in 4 minutes and 2 seconds. Next time, I should do a harder level.

Prototype

My company, Design Company made a prototype of a party popper.

In the beginning, we tested the rubberband. My Design Company and I tested some different materials to make a party popper prototype. For an example, we chose the medium size of rubber band instead of the long rubber band. We changed some ideas to make the party popper work.

Next my group and I tested the weight. For an example, we chose the nut to see how hard or loud it hit the cup. We tested some other parts.

To finish up My group and I assembled all the parts of the prototype. When we assembled all the parts of the prototype. We put the fillings in and see how far it will be able to explode the fillings out.

I learned a lot about making a party popper, prototype, and modeling.
