# Design a school: 10 by 10 grid: assessment

TLF ID L9928

Test your knowledge of percentages and their relationship with proper fractions. Represent given percentages on a 10 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 school. For example, show 15% of the grid as classrooms. 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 first in a series of three objects that progressively increase in difficulty.

#### Educational details

Key learning objectives
• Students interpret a 10 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 10 by 10 grid.
• Checks student’s knowledge and understanding of the relationship between percentages and tenths through required use of a number line.
• Tests student understanding that 100% corresponds to different representations of 1 whole (ie all 100 squares on the 10 by 10 grid, 10 tenths and 1).
• Povides a printable report of the student's performance.
