### Work Sample : Eden

• Grade Commentary

## Mixed operations - Eden : Grade Commentary

### Other Work Samples for:

Eden has demonstrated a limited level of competence in using the four operations to express numbers in different ways. There is some accuracy in the use of basic algorithms but some division examples are incorrect. Correct order of operations has been followed but brackets have not been used. There are some simple, multi-step solutions but most numbers used are below 30. To progress further, Eden could use larger numbers and incorporate fractions, decimals and brackets. This work sample demonstrates characteristics of work typically produced by a student performing at grade D standard midway through Stage 3.

### Grade D

The student has a basic knowledge and understanding of the content and has achieved a limited level of competence in the processes and skills.

## Foundation Statement strands

The following strands are covered in this activity:

• Working Mathematically
Students ask questions and undertake investigations, selecting appropriate technological applications and problem-solving strategies. They use mathematical terminology and some conventions and they give valid reasons when comparing and selecting from possible solutions, making connections with existing knowledge and understanding.
• Number
Students read, write and order numbers of any size, selecting and applying appropriate mental, written or calculator strategies for the four operations. They compare, order and perform calculations with simple fractions, decimals and simple percentages and apply the four operations to money in real-life situations. Students place the likelihood of simple events in order on a number line from 0 to 1.
