WS04 - Number charts and puzzles

Mathematics, Year 1

By the end of Year 1, students connect number names, numerals and quantities, and order numbers to at least 120. They demonstrate how one- and two-digit numbers can be partitioned in different ways and that two-digit numbers can be partitioned into tens and ones. Students partition collections into equal groups and skip count in twos, fives or tens to quantify collections to at least 120. They solve problems involving addition and subtraction of numbers to 20 and use mathematical modelling to solve practical problems involving addition, subtraction, equal sharing and grouping, using calculation strategies. Students use numbers, symbols and objects to create skip counting and repeating patterns, identifying the repeating unit.

 

They compare and order objects and events based on the attributes of length, mass, capacity and duration, communicating reasoning. Students measure the length of shapes and objects using uniform informal units. They make, compare and classify shapes and objects using obvious features. Students give and follow directions to move people and objects within a space.

 

They collect and record categorical data, create one-to-one displays, and compare and discuss the data using frequencies.

Annotations

 

1. Identifies consecutive numbers within a row.

 

2. Recognises the repeating pattern of 1–9 within the decades.

 

3. Completes rows of numbers based on the 1–9 pattern for the units place value.

 

4. Completes columns of numbers based on the 1–9 pattern of the tens place value.

Annotations

 

1. Identifies and writes numbers from the sequence of numbers before and after 92.

 

2. Writes numbers that show the change in the decades place for numbers 10 less and 10 more than 92.

 

3. Shows a standard partitioning of 92 into 9 tens and 2 ones

 

4. Refers to decades and ones when writing a number greater than 10.
