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:
estimation as a check
use multiplication to solve addition and subtraction problems
use doubling halving and trebling
use an algorithm to solve multiplicative problems
solve problems using simple cube numbers

- 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 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…..My next step is to answer questions in Multiplicative Strategies faster so I can go rapidly through them.

Definitions

Void: a completely empty space. Fluorescent:a fluorescent tube or lamp. Vulnerable :exposed to the possibility of being attacked or harmed, either physically or emotionally. Interconnected: connect with each other. Seldom: not common; infrequent.

Example/Non Example	Is a void messy? Why or why not?	No because it’s a blank space in the universe
	Which color is the most fluorescent at night? Why?	I think it's green or yellow because people always where those fluorescents colours.
	Why are elderly people more vulnerable than children? Why?	Because elderly people will know what to do in that situation
	Which is more interconnected; a vine or a dandelion? Why?	Vine because they connect to each other?
	Which is more seldom; the Olympics or an election in NZ? Why?	Election because everyone in the world doesn't know what an election in nz.

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

Word Relationships How might each pair of words be connected?	Vulnerable/Fluorescent	I really want a fluorescent jacket.
	Void/interconnected	Wormholes connect through voids.

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.
	When I wake up early the morning it is really dark and have to find my way to the switch and some times I  my toe trying to get to it.
