Numeracy+Strategies



Try these BEDMAS problems:

Go to this [|website] to work on BEDMAS (they call it BODMAS but it's the same thing :))
This Practice Test will be used in class:

Examples of Number Strategies (not Algorithms):
=Tidy numbers=

Where we make numbers easy to add, like multiples of 10.

Eg: 54 + 36

= 60 + 30 OR 50 + 30 + 10

= 90

=Compatible numbers=

Where numbers that are the same can be crossed out

Eg: 8 + 3 - 8

=3

Eg 2: 5 + 3 + 6 - 8

=8 + 6 - 8

= 6

=Up over Tens=

Where we add by splitting up numbers into parts to make tens

Eg: The farmer has 28 cows. She buys some more cows at the stock sale. Now she has 33 cows. How many cows did she buy?

28 + @ = 33

33= 28 + 2 + 3

@= 5

=Jumping the Number Line =

Jump through a tidy number on a number line to solve problems like 17+_= 91

Eg: 36+17=

Add/Sub/Multiplication and Division strategies (Eg: tidy numbers, number lines, halving and doubling)

factors, multiples, primes

squared numbers (other exponents may be included too, Eg: 5 the power of 3)

square roots

BEDMAS (order of operations)

Estimating

Place value (Eg: If 43 means there are 4 tens; what does the 4 mean in the number 4357?)

 * Here are some practice sheets:**



=For the Assessment on Numeracy strategies (working essential) AND Geometry and Measurement (tested at the same time).= Use your homework book to revise as well as your notes. Also check the pages of our wiki "Numeracy Strategies" and "Geometry and Measurement" I've added some practice sheets in both

= You will need to know: = You will need to demonstrate at least two different ways of solving a problem as well.
 * How to show working to demonstrate 'how' you solve equations (eg: draw a numberline, find numbers that add up to 10 etc)
 * You will need to know how to solve unknown angles in a triangle (using the rule: angles in a triangle add to 180*)
 * You will need to know how to solve unknown angles in an isosceles triangle - where two sides, and angles are the same
 * You will need to know how to solve unknown angles on a straight line (using the rule: angles on a straight line add to 180*)
 * You will need to know how to solve unknown angles on verticle lines (using the rule: verticle angles are equal)
 * You will need to know how to solve unknown angles at a point (using the rule: angles at a point add to 360*)
 * How to measure a reflex angle (an angle larger than 180; ie: you measure the smaller angle and subtract that value from 360*)
 * How to find the perimeter of basic shapes (not cicles)

=Tidy numbers= Where we make numbers easy to add, like multiples of 10. Eg: 54 + 36 = 60 + 30 OR 50 + 30 + 10 = 90

=Compatible numbers= Where numbers that are the same can be crossed out Eg: 8 + 3 - 8 =3

Eg 2: 5 + 3 + 6 - 8 =8 + 6 - 8 = 6

=Up over Tens= Where we add by splitting up numbers into parts to make tens

Eg: The farmer has 28 cows. She buys some more cows at the stock sale. Now she has 33 cows. How many cows did she buy?

28 + @ = 33 33= 28 + 2 + 3 @= 5

=Jumping the Number Line =

Jump through a tidy number on a number line to solve problems like 17+_= 91 Eg: 36+17=



a) Geri-Lee has 18 biro pens and 13 felt pens in her pencil case. How many pens does Geri-Lee have in her pencil case in total?

b) Tchanze is given $45 as a birthday gift from his Nana. He wants to buy a pair of rugby boots for $63. How much more money does he need to buy the boots?

c) Cameron has 31 merits from school; Justice has 27 merits. How many merits do Cameron and Justice have altogether?

d) Ashley collects stickers. She has 27 in her collection; her friend Jesse gives her 5 more and then her cousin gives her 3 more. On her way home she loses 8. How many does she have left?
