Essential Agreements.. I agree to

•  Show principled by raising up my virtual hand (use the raise hand button) when I want to speak
• Be caring by showing respect each other and use kind words
• Use communication skills by listening to the lesson and stay focus using self-management skills
• Have fun learning

What do you understand about pattern from the last lesson?

K: Know that multiplication is repeated addition and that division is repeated subtraction

U: Numbers exhibit patterns and relationships that can be observed and described

D: Able to identify patterns of a number series, explain and use the relationship between multiplication, addition, division and subtraction to solve problems.

Minty's condominium is experiencing water shortage. Minty saved 100L of water in her personal water tank. She drinks 20L of water everyday. How many days she can survive with her water tank?

1. 50days
2. 40days
3. 4 days
4. 5 days

What strategy you used to find your answer? Why?

Create a number series to describe your answer on question 2

Hidden Learning Objective

If we use multiplication/addition for increasing number patterns and division/subtraction for decreasing number patterns, what can you say about the relationship between multiplication and division?

The inverse

relationship between multiplication and

division

Did you get it right? ^^

Success Criteria

I can

+Identify increasing and decreasing pattern

+Complete a number pattern

+Explain multiplication and division as repeated addition and subtraction using words and graphic

+Think creatively and independently

Homework: Self assessment by reflecting how well the success criteria was achieved, what went well, what you learnt and how can you improved. How do you apply patterns in math in daily life?

Extension

Create  a word problem involving what you learnt today.

(Know that multiplication is repeated addition and that division is repeated subtraction). Use key concept (Change or Responsibility)

Differentiated
