    We reviewed the sorting of polygons and quadrilaterals. Take a look here to make sure you understand.

    Try any of the Ch. 7 activities.

  4. Hailey,

    We worked on a worksheet that covered converting square metres into square centimetres. Go to http://www.nelson.com/nelson/school/elementary/mathK8/math6/studentcentre/studtryout.html and look at the Ch. 8 activities.

  8. Hailey,

    Chapter 8:2 ---> Area of a parallelogram.

    The key thing to remember is that the A = Base x Height.

    Base is the length of the bottom of the shape and the height is measured ninety degrees straight up from the base.

    HTH,

    Mr. R.

  9. What about if your side length is still the same length as your height,then what is the point of the 90 degree angle thing?

  10. Genna,

    Great question. The side length would only be the same as the height, IF, that side is already a ninety degree angle. This is shown in question 4b, I believe.

  11. I wasnt there on friday and the homework from thursday night i dont understand question 6. It says that you have to make a acute trinangle,right triagnle and a obtuse triangle and the area has to be 6cm2. I dont understand how you would make a Obtuse Triangle or an Acute Triangle because you would need a right angle but a acute triangle and a obtuse triangle only have those angle measurements.

  12. Holly,

    Don't forget that the height of the triangle is measured 90* from the base. You do not necessarily need a 90* (right) angle in the triangle. An acute triangle has ALL acute angles and an obtuse triangle has ONE obtuse angle. (It's impossible to have all obtuse angles). Hope this helps.

  14. i dont understand how u do the mesurment of a triangle

  15. Cody,

    You need to have two dimensions (measurements) in order to calculate area of a triangle. The first is the base and the second is the height. The base is the bottom of the triangle and the height is a 90 degree line from the base to the highest point in the triangle. Once you have those two numbers, you need to multiply them together. You would then have to take that number and divide it by two. Don't forget that a triangle is half of a parallelogram. Go to www.mrrumsby.com and check out the area of a parallelogram and area of a triangle lessons for more help.

  18. Bailee,

    There were several review questions that we worked on in class. If you go to the Nelson site, located in the 'Links' section of the website, there are questions there that you could work on as a review. If you have any other questions, come in early tomorrow and I will help you through them.

    Mr. R.

  20. Bailee,

    I will be helping move the risers over to Simcoe in the morning. However, we can go over some of the math during the break. Also, read the reply above. The Nelson site is great for a little extra help.

    Mr. R.
