Using a range of multiplicative strategies

In Maths we have been learning to use a range of multiplicative strategies when operating with whole numbers. 

Here is a link to our online modelling book 

The strategies we have been learning are:

- Estimate the reasonableness of large problems like 1 788 – 891. Could 497 be right?

- Use multiplication to solve addition and subtraction problems eg. 

   64 – 48 = as (8 x 8) – (6 x 8) = 2 x 8= 16

- Use doubling / halving, trebling/ thirding and adjusting to solve multiplication problems,

  eg.  12 x 50 solved as 4 x 150= 600

- Use an algorithm to solve multiplication problems.

- Solve problems using simple cube numbers .

- Use an algorithm to solve division problems. 

Here is a link to my Multiplicative Strategies Assessment which shows that I know why and how I use particular strategies. This doc also has screenshots to show which IXL activities I have completed as part of my learning. 

My next step in my Maths Learning is Measurement.

Vocab activity

Year 7/8: I can use my growing wide range of academic and content-specific vocabulary to understand texts.

Name of Text: Underground Explorers

Definitions

Void: an empty space or vacuum. Fluorescent: able to give off visible light after being exposed to a source of heat, light, or other form of energy Vulnerable: able to be hurt or injured Interconnected: to connect or cause to be connected one to the other or others. Seldom: not often; rarely.

Example/Non Example	Is a void messy? Why or why not?	yes because you don't know what's gonna be in the void.
	Which color is the most fluorescent at night? Why?	red because it is a bright colour.
	Why are elderly people more vulnerable than children? Why?	because they can't run or defend themselves from others.
	Which is more interconnected; a vine or a dandelion? Why?	Vine because it is grass connected together.
	Which is more seldom; the Olympics or an election in NZ? Why?	Olympics because it's every 4 years and a NZ election is 3 years.

Word Associations	The plants in the garden are die during a frost	vulnerable
	There were lots of different paths that joined each other	interconnected
	I made a shot from halfway while facing backwards.	seldom
	We are still exploring  outer space.	void
	I can find my key ring easily in the dark.	fluorescent

Word Relationships How might each pair of words be connected?	Vulnerable/Fluorescent	you can be vulnerable when in light because everyone else can see as well.
	Void/interconnected	void is connected with random things.

Extended Writing	Think of a time when you felt as though you were in a void or when you saw something that happens seldom. Write a paragraph about this.
	On Saturday before my team's game we watched another game because we got there early, then we saw a guy no looked and kick the ball and the ball hit the crosshairs without looking and that happens seldom.
