Core Skills Analysis
Math
Ella worked through a 7th grade summer review math worksheet that focused on fractions, decimals, order of operations, rounding, and ratios. She evaluated and simplified mixed-number expressions by adding and subtracting fractions with unlike denominators, which showed her practice with equivalent fractions and fraction computation. Ella also renamed fractions as decimals, computed decimal sums, and applied order of operations correctly in expressions like 10 - 5 × 0 - 2 and 16 ÷ 2 × 4, which strengthened her accuracy with multi-step numerical reasoning. In the final problems, she rounded numbers to different place values and converted a ratio involving cups of raisins and pecans into whole-number form, demonstrating that she was connecting abstract number skills to practical ratio reasoning.
Tips
To deepen Ella’s understanding, try having her create her own mixed-number and decimal problems using real-life examples like recipes, shopping, or sports statistics so she can practice choosing the right operation and place value in context. She could also sort a set of expressions into “fraction work,” “decimal work,” “rounding,” and “ratio” categories, then explain which strategy each one requires and why. A hands-on extension would be to measure ingredients for a simple snack mix and rewrite each measurement as a fraction, decimal, and ratio, helping her see how the same quantity can be represented in different ways. For extra challenge, give her a few incorrect worked examples from the worksheet and ask her to identify the mistake, correct it, and describe the math rule that was violated.
