Texbook (1-3)

1. Explain why the area of a rectangle and the area of a parallelogram made from the rectangle are the same. Include diagrams with your answer.

If you take the triangle and move it over to where it fits, it's still the same shape, just at a different angle.

2. Deepa determined the area of this parallelogram to be
5cm2.

a) Deepa did 2.5 x 2 which is 5. Deepa was supposed to find the height which the height was 2
cm. b) b x h = 4 cm 2cm x 2cm = 4 cm2




3.
These parallelograms are drawn on centimeter grid paper. What is the area of each parallelogram?


a) 3cm2

b) 6 cm
2













Here is a link to practice with.

Madeline,I like your post,you did everything that we should do in a post.(which makes it hard to give suggestions)I think the only thing you can try to improve is to change the size of the font, try to make your answers bigger so people see it right away.

Hi Madeline! Your scribe post is AWESOME! I especially like the link you added, it was fun and very helpful. To make your scribe post better next time I think you should make your font a little bigger, so it's easier to see. Here is a video that I think you should add on how to find an area of a parallelogram.

Hi Madeline! Great work on the scribe post! I agree with you on all of your answers. Yes, Deepa did make a mistake by multiplying 2.5 and 2 together. And yes, I too got the answer 4! Also, I liked how you added picture with you explanations. It made your explanation even clearer. Awesome Job!
