Today, we continued our learning about probability and did several hands on tasks around the probability continuum. Students learned about proper Math vocabulary around probability: Certain, likely, even, unlikely, impossible…… and created a variety of spinners to reflect a criteria. Final task for the day was an assessment:
Our warm up question for tomorrow:
Explain why it is impossible to make a collection of marbles to match this description:
It is impossible to pick red.
It is certain to pick blue.
It is very unlikely to pick green.
Working on fractions in grade 4/5 today. Equivalent fractions were explored as well as proper and improper fractions. We talked and explored how to turn an improper fraction into a mixed number. Our activities with cuisenaire rods allowed us some great learning.
If the brown rod is the whole, what is 5/4 this?
If the brown rod is the whole, what is 7/8 ?
If the purple rod is 2/3 of the whole, what does the whole look like?
Research the origin of the word “fraction” and write a summary of the origin on a piece of paper. Have fun! Due Monday!
As we learn all about metric conversions, the students are working on solving problems which involve a conversion….
And of course….when we convert into centimeters, which is what our question is asking us to do….the answer is 5.0 centimeters or 50mm. Great work Chaim, Taylor and Lauren!
Throughout the week, I would like the students to practise their math skills at home using prodigy math. Its an engaging and fun way to refine math skills and I promise you will get no complaints for completing homework. If you remember, I have already sent home their login username and password. I have assigned the students content within this game which is reflective of our learning in the classroom!

Parents, I am sending home a sheet of multiplication tables with the students today. Every other day we are completing 5 minute math drills to improve the students multiplication recall. By memorizing their times tables each night, this will help them when they move on to x by double digits and division in future grades. I would like them to take one table each night and try to memorize. We have already worked on the 0,1, and 2 tables and that quiz is coming home tonight! On Friday, we will have a drill for the 3 and 4 times tables. We will then continue with our focus of measuring length, area and perimeter.

Students have been learning about the following skills/concepts in Geometry.
Transformations: A transformation is a rule that results in a change of position, orientation or size. They include translations (slides), reflections(flips) or rotations (turns).
Reflections: A flip of a 2D shape; each point in a 2D shape flips to the opposite side of the line of reflection, but stays the same distance from the line.
Translation: A slide of a shape; the slide must be on a straight line.
Rotation: a turn of a 2D shape; each turn can be identified as a 1/4, 1/2, 3/4 or full (1) turn.
Congruent: When a shape is congruent it means it is identical in size and shape. In order to be sure a shape is congruent you can check 2 ways.
1) tracing paper – trace the shape, cut out, match to other shape
2) Ruler + Protractor – Measure all side lengths and angles to see if they are identical.
Prism: A 3D shape with opposite congruent bases. The other faces are parallelograms (usually rectangles).
Pyramid: A 3D shape with just one polygon for a base. The pyramid is named for the shape of it’s base. The other faces are triangles and meet at a single vertex. (eg: square based pyramid)
Net: A net is a group of 2D shapes that you can fold to create a 3D solid. Students should be able to draw nets for 3D solids and identify which 3D shapes can be made from a net.
We have looked at, learned about and examined the attributes of 2D shapes and how these shapes can flip, slide and turn ( reflect, translate and rotate). This week will move on to examine the properties of 3Dimensional solids. We will be examining number of vertices, faces, bases that these shapes have and sort them according to their attributes. You can practice your skills here!
