Unit 1: Place Value and Numbers

http://www.kidsmathgamesonline.com/facts/history.html Understanding Place Value

Examples of place value:   These are called Base Ten Blocks.We use real block or draw shapes to represent numbers. Ask your child what these shapes mean.

Standard form= 134

Expanded form= 100+ 30 +4

Word form= one hundred and thirty four  Extending place value to 1000

Numbers, digits and numerals https://www.mathsisfun.com/numbers/numbers-numerals-digits.html

Partition: This is when we pull numbers apart to see their place value.It is similar to using expanded number form.  Number Bond or Number Fact:

Most textbooks define number bonds as the different pairs of numbers which make up the same number. E.g. All the number bonds for 10 are: 1+9, 2+8, 3+7, 4+6 and 5+5.

Number bond is typically represented using a picture consisting of 3 circles connected by 2 lines. See the examples below.   It is important to learn your number bonds up to 20.

For a challenge you could also learn your bonds up to 100!

Number Lines (Counting on and backwards using a number line) At school we often talk about different ways to represent numbers.Explain the pictures below to your family so that you can all talk about numbers using the same language.

A SET

A collection of “things” (objects or numbers, etc). Each member is called an element of the set. There should be only one of each member (all members are unique).

An example: {1,2,3,4} is the set of counting numbers less than 5

Draw a picture In a tens frame Using base 10 blocks (see above) Tips for parents and home to school connections:

Ask your child where they see numbers at around them

Ask your children to add up prices when you shop or eat at a restaurant.

Ask your child to count and group items at home
