| Victorian Curriculum outcome : Solve word problems by using number sentences involving multiplication or division where there is no remainder. Use equivalent number sentences involving addition and subtraction to find unknown quantities | |||
| Task description : Students create eight number stories, two involving addition, two involving subtraction, two involving multiplication and two involving division. 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. | |||
