Learning Target for Wed march 15, Thursday March 16th is a review of quadrilaterals and finding area.
You need to know: quadrilaterals, parallelograms , rectangles, squares, rhombus, trapezoid, obtuse. acute, congruent.
We will be investigating what we know about area and using it to find the area of rectangles (review), parallelograms and triangles. We will use 5 identical rectangles of grid paper. and use them as follows.
1. We use to demonstrate the area of all the rectangles. 2. we make into a parallelogram and work on the area. 3. make a different parallelogram and work on the area. We make hypotheses about calculating area of a parallelogram and test them. 4. and 5. are made into parallelograms and then cut in half ot form triangles. We make and test hypotheses about calculating the area of all/any triangles. This is a hands on investigation and anyone who misses it needs to do it during the first HOT after spring break.
Homework IXL AA8, AA9 – from last week’s graphing lesson
Learning Targets for Friday 18th, Monday 21
Today we use the knowledge of area of quadrilaterals and triangles gained in last class to find areas and to “de-compose ” complex figures into quadrilaterals and triangles to find the total area. its a practice and work day. We will investigate number sense and changing dimensions affect on area with a patty paper activity.
Classwork- do either a or b:
A: ch 10-1 page 536: 8, 15, 18, 19, 10 page 542/543 do 11,8, 17, 18, 28,29,30
B: Green book page 410, 411 # 10, 12,15,17, 21 24,25,26, 27, 29,30,(31 is a challenge question and is optional)
Homework IXL bb23, bb24
Learning Targets for Tuesday, March 22, Wednesday, March 23
Volume of cubes, rectangular prisms and right triangular prisms.
We start with understanding the above terms. https://www.mathsisfun.com/definitions/rectangular-prism.html will help. Be sure you understand that volume has 3 dimensions so units are cubed or to the third power. units x units x units. Then do the volume task below. be sure to show all work and explain.
homework IXL bb26 and bb 36
th, Thursday March 24th, NO MATH CLASS ON FRIDAY MARCH 25 TH DUE TO FROG DAY
No homework, Rest and Relax over spring break!
Nets are flat shapes that fold into 3d shapes. We will work on nets and then we will calculate the surface area of cubes, rectangular prisms and right triangular prisms. Try to discover which nets will form a cube in the lesson link below.
Then trace a small object and try to make a net that will the object. A small book should be quite doable. We will not be doing any cylinders (that’s next year) but you may want to try a triangular prism. The surface is the total area of all the faces. Find the surface area of your net. bring your net and your calculations of surface area to class after the break
