LITERACY

 

MATH

When we learned the formula we understood EXACTLY why it works….because the formula for volume is the area of the prism face (a rectangle) multiplication lies by the height of the prism.

So the formula has to be applied in a particular way:

V = length x width x height

where the length x width is the area of the rectangular face

LEVEL 4

We noticed that we can calculate volume of a rectangular prism from two (2) points of view….here we have highlighted two rectangular face views.

AGAIN, the order of numbers in the formula are important and apply directly to the order: length x width x height of the prism

 

Another example:

 

Our next step was to work in groups of three to under how we would find the volume of a TRIANGULAR prism. We’ll take a close look at those tomorrow.

MATH

Surface Area – What makes a good answer? (Successfully Criteria co-created with the class)

 

 

Ms Fawcett presented us with the answers to homework last night….chose our  partner ….and we gave a partner feedback on how well they met the success criteria!

Finally….We completed an assessment question independently. Tomorrow we will sit in a circle and pass the work around (without names) and moderate each other’s work using the success criteria!

MATH – Measurement & Geometry

We followed up yesterday’s grade 5 review of Volume of a rectangular prism with 3D drawings of prisms. Using triangular dot paper, we learned to draw the prisms that we made with linking cubes. ALL the rectangular prisms had a volume of 12 cm cubed.

We discovered that there are 4 rectangular prisms with a volume of 12 cm cubed.

V = ℓ x w x h

V = 1 x 1 x 12

= 12 cm cubed

OR

V = 2 x 2 x 3

= 12 cm cubed

OR

V = 1 x 3 x 4

= 12 cm cubed

OR

V = 1 x 2 x 6

= 12 cm cubed
