# Ma1 Using and applying mathematics

## Rows of coins

### Teacher's notes

• Uses trial and improvement to look for different combinations that satisfy the first criterion.
• Makes changes based on calculations made.
• Chooses own method of recording.
• Recognises halves and doubles.

### Next steps

• Solve more complex problems with a greater number of criteria to be met.
• Work systematically to find more than one possible solution.

## Treasure hunt

### Teacher's notes

• Works systematically to find different combinations.
• Checks each combination against the set criteria.
• Explains method of working.
• Chooses to record results in a table.
• Reasons that he has found all possible combinations as both pirates must have at least one jewel, to make it fair!

## What the teacher knows about Greg's attainment in Ma1

Greg uses trial and improvement to solve problems and is beginning to work systematically. He listens to classroom discussions about how to solve a problem, and then selects his own method from those discussed. He chooses appropriate operations and makes use of suitable equipment, such as coins or different coloured cubes.

He organises his own work and draws tables to record results. He explains methods chosen to solve problems. He sometimes checks results against original criteria.

With encouragement Greg looks for patterns, but does not always find them. In a similar way, he may not find all possible combinations. When prompted, he is usually able to explain his reasoning. He poses problems for others to solve.

## Summarising Greg's attainment in Ma1

Greg is best described as at secure level 3 in Ma1. He tries different approaches to overcome difficulties. He records his results in an organised way and is beginning to explain his thinking. To improve, he needs to develop his knowledge of number patterns to help him make predictions.
