Percentages - Assessment (1)

In this comprehensive assessment, students are tested on their understanding of percentages through a variety of exercises. The first task involves identifying the shaded percentage of different hundred grids, which is a visual representation to aid in understanding basic percentages such as 50% and 25%. Following this, students use bar models to calculate percentages of given weights, specifically finding 50% and 25% of 140kg. The assessment continues with more practical applications, where students shade 24% of a hundred grid and use a bar model to determine various percentages of the number 90, including 10%, 20%, 80%, and 5%.

The assessment also includes a self-evaluation section, where students can rate their confidence with percentages on a scale from 1 (not confident) to 5 (very confident). Additional questions involve interpreting a percentage bar chart to determine the colour distribution of counters within a box. Arithmetic problems challenge students to find the whole number when given a percentage of it, such as finding what number has 50% equal to 36 or 10% equal to 4.5. The assessment extends to real-life scenarios, where a character named Esin spends a percentage of her money on a computer game, and students must calculate the expenditure. Lastly, the assessment presents a conversion table where students fill in missing values to match percentages with their equivalent fractions and decimals. In a final problem, students calculate how many apples are left after a certain percentage is used for juice and pies from a bag of 150 apples.
