Counting

Posted by year2

In Maths the students have continued to work on place value and counting along with problem solving. It is important for every child to continue to regularly practice counting forwards and backwards, crossing the decade (ten number) from a given number. Please use a 100s chart to practice this with your child at home. We have been working on this in our classes so ask your child to explain how it is done. Another practical example is to have your child to count out money (using $2, $5 or $10 coins), then practice counting back.

Below are some games and activities to reinforce these ideas at home.

Maths – Place Value

Posted by year2

Our current math focus is developing understanding of place value in numbers.

To begin with, students learn to recognise patterns to 5 on fingers and in 10s frames, and then they extend this knowledge to numbers to 10. The idea of having instant identification is that kids start to develop the understanding that while numbers can be formed in different ways, they are still the same number (e.g 4+3 = 7, so does 5+2 and 6+1).

The next step on from pattern recognition is to understand the value of the digits in numbers. We regularly use place value houses to show how the position of each digit affects it’s value. Our main focus is on the first place value house, often referred to as the ‘trend-setter house’ which includes the hundreds, tens and ones/units. Kids are also learning to expand out numbers to reinforce the idea of place value (e.g. 793 is not simply 7 and 9 and 3, it is 700 + 90 + 3).

Below are some games and activities to reinforce these ideas at home.

Pattern, Function and Skip Counting

Pattern and Function

During Term 1 students inquire into Pattern and Function. Students learn to identify, name, extend and show patterns in various ways. We explore patterns around us, make repeating patterns and determine features of patterns. Students translate patterns, creating them in different ways and using a 100 chart to find number patterns.

Our ‘Central Idea’ is:

Patterns have repetitive features that can be identified and described.

Our ‘Lines of Inquiry’ are:

– Characteristics of a pattern

– Different ways to make, describe and record patterns

– How patterns help us to predict

Skip Counting & Patterns

As part of their learning about pattern and number the students have been skip counting with numbers to 100.

  •      Practise skip counting (by 2′s, 5′s and 10′s) with or without a hundred chart. 
  •      Practise locating numbers on and navigating the 100 chart (10 more, 10 less, 1 more, 1 less, etc.) and finding patterns on the hundred chart using Splatt 100. You can also practise these skills by playing Starship Games.
  •     Pattern Mania
  •     Colour Patterns
