Assessment resource Design a farm: 5 by 10 grid: assessment

TLF ID L9929

Test your knowledge of percentages and their relationship with proper fractions. Represent given percentages on a 5 by 10 grid. Also show them on a number line marked in tenths. Allocate squares on the grid to match the given percentages for different parts of the farm. For example, show 18% of the grid as grazing land. Add each percentage to the number line by moving a bar along the line. View and print a report of your results. This assessment object is the second in a series of three objects that progressively increase in difficulty.



Educational details

Key learning objectives
  • Students interpret a 5 by 10 area model in relation to percentages.
  • Students interpret number line models in relation to fractions and percentages.
  • Students use the relationship between fractions and percentages to solve problems.
  • Students identify fractions and percentages that total 1 whole.
Educational value
  • Assesses student's ability to relate percentages to a 5 by 10 grid.
  • Checks student’s knowledge and understanding of the relationship between percentages and tenths through required use of a number line.
  • Requires students to use proportion when allocating numbers of squares on the grid to each of the given percentages.
  • Tests student understanding that 100% corresponds to different representations of 1 whole (ie all 50 squares on the 10 by 5 grid, 10 tenths and 1).
  • Provides a printable report of the student's performance.
  • Includes a mechanism for the teacher to comment on the student's learning progress.
