• Grade Commentary

## Recording my strategies - Casey : Grade Commentary

### Other Work Samples for:

Casey has displayed an elementary knowledge and understanding of numerical concepts through the mental and written computations shown. Casey has been unable to explain any mental strategies used to complete the addition and subtraction tasks and the answers indicate a lack of understanding of the operation of addition. There is limited use of reasoning and mathematical language. This work sample demonstrates characteristics of work typically produced by a student performing at grade E standard at the end of Stage 2.

### Grade E

The student has an elementary knowledge and understanding in few areas of the content and has achieved very limited competence in some of the processes and skills.

## Foundation Statement strands

The following strands are covered in this activity:

• Working Mathematically
Students ask questions and use appropriate mental or written strategies, and technology, to solve problems. They use appropriate terminology to describe and link mathematical ideas, check statements for accuracy and explain reasoning.
• Number
Students count, order, read and record numbers up to 9999 and use mental and written strategies, including the formal written algorithm, to solve addition and subtraction problems involving numbers of up to four digits. They use mental strategies to recall multiplication facts up to 10 x 10 and related division facts and use informal written strategies for multiplication and division of two-digit numbers by one-digit numbers. Students model, compare and represent simple fractions and recognise percentages in everyday situations and they model, compare, represent, add and subtract decimals to two decimal places. Students perform simple calculations with money and conduct simple chance experiments.
