Measuring and Counting

Unit 4

Focus Points for Investigation 4:

Linear Measurement: Understanding length and using linear units:

Understanding what length is
Comparing lengths of different objects
Developing strategies for measuring the length of an object

Counting and Quantity: Developing strategies for accurately counting a set of objects by ones:


Connecting number words, numerals and quantities
Keeping track of a growing set of objects
Developing and analyzing visual images for quantities up to ten

Whole Number Operations:
Making sense of and developing strategies to solve addition and subtraction problems with small numbers

Combining two amounts
Decomposing numbers in different ways
Adding to or subtracting from one quantity to make another quantity
Exploring combinations of a number (e.g. 6 is 3 and 3 and also 5 and 1)

Counting and Quantity:

Developing an understanding of the magnitude and postion of numbers:

Comparing two quantities to determine which is more

Whole Number Operations:

Using manipulatives, drawings, tools and notation to show strategies and solutions:
