| Victorian Curriculum outcome : Explore the use of brackets and order of operations to write number sentences | |||
| Task description : Students create eight number stories, two involving addition, two involving subtraction, two involving multiplication and two involving division. Four of these stories must involve the use of brackets. For each story, the student must write the story, draw a picture and write a number sentence with a box representing the unknown number. They must then solve each story using inverse operations (you will need to explain what this is). | |||
| Assessment options : Photographs of drawings; digital equivalents using Paint or similar. | |||
| Teacher notes : Students can really struggle conceptually with this task: many donโt seem to understand the difference where the unknown is at the end of the story compared. For students lacking imagination, provide a scaffold to help them create a story: the video provides models which can be easily adapted to involve addition, subtraction, multiplication and division. Be careful with the subtraction stories: if the student has the unknown at the beginning of the story, things can get confusing. | |||
