Olympics 2020

The olympics are leading international sporting events featuring summer and winter sports competitions.

Addition and Subtraction

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

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

Rounding and compensating is rounding the added or subtracted number to the nearest tidy number, then compensating for the rounding. Compensating is done by spitting 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 numbers get too big to be solved with basic facts.

Party Popper

My group, Applemelon created party poppers with the same design.

First dissucusd what the design we should come up with. we drew our design on a piece of paper. We stick our design on a cup.

Next we added a hole to the bottom of our cup. so we can put the rubber band through the hole. we used a tooth pick to stop the rubber band from coming out.

Last we added the filling. we used 15 small pom poms and 15 glitter sticker. each person had 5 pom poms and 5 glitter sticker. 

The experience was amazing because it helped me to work as a group better. The party popper worked well. 

Basic Facts Boxes

I completed a speed demon challenge.
I got 100/100 in 3 minutes 57 seconds.
I think I need to go on a harder level.

SSR Selfie Ninja Kid

  I read 27 pages of Ninja Kid 2.

This story is about a kid name Nelson. He got his ninja powers from his dad but his dad's twin brother want to captured Nelson.

I dislike Nelsons dad's twin brother because he want to captured Nelson.

Basic Facts Boxes

 I did a speed demon challenge subtraction up to 5.

I did it in 4 minutes 33 second. I got 100/100.

I think I need to go on a harder level

Party Popper Prototype

My group, Applemelon made a prototype for a party popper.

In the beginning, we discussed the different parts of the model. For example, we used a long rubber band instead of the thick rubber band. We figured out that a long rubber band has more force than the thick rubber band.

Next we tested the prototype. We discussed that we should use pom poms for the filling.

To finish up we used a nut for the striker so the pompoms can explode out of the cup. We thought about what we needed to change to make it better. 

I learned a lot about prototype and modeling
