Compound and simple sentences

This week we learnt what a compound and simple sentence is and means.

A simple sentence is a actor (someone) or action (something).

A coumpund sentence is two simple sentences stuck to gather, and using certain fanboys which are, for, and, nor, but, yet, and so.

I liked learning about these but I wasn't really letting my group have a turn at writing.

 

Addition and subtraction

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

Counting on is adding foward 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 number, then compensating for the rounding. Compensatng is done by splitting the new number into the old number and the leftover.

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

Party Popper

My company, Design Builders, mass produced and tested to see if our party popper worked.

First We practised our harry potter design on a piece of paper then we drew it on our cup. We drew lightning bolts, Harry Potter glasses, a broomstick, and a wand. The design turned out good but we didn't draw the same design of harry potter.

Next we got the materials to build our party popper. We got long rubber bands and a half toothpick.  The Design builder pushed the rubber band in through the hole in the cup and attached the half toothpick.

Lastly, the Design Builders did the weight and the filling for the weight we used on a piece of paper. For the filling we used pom poms and glitter stickers.  After that we tested to see if our company's party popper works.

I enjoyed making a party popper. With Harry potter design. Our party popper didn't work properly because not all of the filling came out. Next time I'm going to use a nut.

Party popper prototypes

My company, design builder, made a prototype on the party popper we designed.

First we modelled what we needed for our prototype. For example we used a medium rubber band and a thick rubber band. The medium rubber band was better because it hit the cup harder, and the thicker rubber band hit the cup softer. The most efficient rubber band was the medium rubber band.

Next we put together the parts we were going to use. We had a paper cup but decided to change it to a plastic cup because it was more efficient when using the weight. For weight we used paper because it hit the cup harder.

Last We modeled our fillings we used fuzz balls because it was easier to pick up. If we used confetti it would be hard to pick up and yarn would disintegrate. We used medium fuzz balls because they were small.

I enjoyed designing our prototype because we learnt what prototype means. I would have liked to use a nut and bolt for my weight because it's heavier and hits harder. We think we could make our party popper better if we used stronger weights. 

Trebuchets

A trebuchet is a medevil military weapon used to knock down castles.

I wrote an explanation about how trebuchets work using cause and effect sentences.
