## Weekly Primary Math Task – Nov 13, 2016

**Up-and-Down Staircase:**

One block is needed to make an up-and-down staircase, with one step up and one step down.

4 blocks make an up-and-down staircase with 2 steps up and 2 steps down.

How many blocks would be needed to build an up-and-down staircase with 5 steps up and 5 steps down?

Explain how you would work out the number of blocks needed to build a staircase with any number of steps.

## Weekly Primary Task – Oct 30, 2016

I used digit cards to create a 2-digit number pattern. The wind blew the cards and mixed them up. How might you place the loose digit cards into the following to complete a pattern? How do you know? How might you extend the pattern?

## Weekly Primary Task – Oct 23, 2016

Allow students time to explore the attributes of various 3-D shapes. Have them identify the faces, edges and vertices of the 3-D shapes? Present various problems for them to solve:

- If you had 3 cones, 2 cylinders and a sphere, how many faces would you have? How do you know?
- You have 1 cube and your friend has 4 cylinders. Who has more faces? How do you know?
- I have some objects and in total I counted 8 faces. What might the objects be? Explain your thinking.
- I have a collection of objects that have 7 faces and a point. What shapes could they be? Explain your thinking.

Have the students create their own clues to create a problem.

Take your class outside and have students collect 5 of an object (leaves, rocks, etc..). The task is for students to work in groups and find different ways to make 5. How many ways can you make 5? How can you show all of your ways?

Extensions: How about 4? How about 6?

## How Many Are Hiding?

#### September 25, 2016

__Materials:__

- 10 or more snap cubes / objects per player
- a cup for each player

__Task Instruction__

- In this activity each child has the same number of cubes and a cup
- They take turns hiding some of their cubes in the cup and showing the leftovers
- Other children work out the answer to the question “How many are hiding,” and say the full number combination

Example: I have 10 cubes and I decide to hide 4 in my cup. My group can see that I only have 6 cubes. Students should be able to say that I’m hiding 4 cubes and that 6 and 4 make 10.
