Constant of Proportionality (Tables) is a Grade 7 mathematics worksheet with 21 multiple-choice questions on interpreting proportional relationships in tables. Students identify the constant of proportionality, calculate missing values, decide whether tables are proportional, select the matching equation in the form y = kx, and interpret constants with units such as dollars per hour and miles per hour. Several items also ask students to connect a table to its graph or compare multiple tables. This free printable worksheet helps students move from repeated ratios in a table to the equation that represents the relationship. It is suitable for guided practice, independent review, or a quick formative check after introducing proportional relationships. A complete answer key is included so teachers can review errors in selecting k, writing y = kx, and distinguishing proportional from non-proportional tables.

FAQs

What does the Constant of Proportionality (Tables) worksheet cover?

This Grade 7 worksheet uses 21 multiple-choice questions to build skill with finding the constant of proportionality from tables and expressing it as y = kx. Students also determine missing table values, classify relationships as proportional or non-proportional, identify matching equations, and interpret constants with units such as dollars per hour or miles per hour.

How can I use this worksheet to teach finding the constant of proportionality from tables?

First model how to compare corresponding y- and x-values to find k, then show how that value produces the equation y = kx. Use the worksheet’s classification items to ask students to justify whether every row has the same ratio, and use the missing-value questions to connect the constant to prediction. Finish by discussing how a table, its equation, and the represented graph describe the same proportional relationship.

What mistakes should I watch for when students complete this proportionality tables worksheet?

Students may divide in the wrong order and choose the reciprocal of the constant, especially in items involving fractions or rates. Watch for students who identify a repeated-looking number without checking y ÷ x across the table, confuse k with x or y when selecting an equation, or label a table proportional without verifying all corresponding pairs. In the missing-value items, check that students multiply by k rather than add a fixed amount.

How do I assign and grade this Constant of Proportionality worksheet?

Wayground provides this worksheet as a printable PDF and as a digital quiz, with a complete answer key for all 21 multiple-choice questions. For printable submissions, you can scan student work with the Wayground for Teachers app to support grading and review of errors in calculating k or identifying proportional tables.

How can I differentiate this worksheet for students who need support with tables and equations?

In the worksheet’s Advanced Settings, adjust font spacing or increase the font size to make the table-based multiple-choice items easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language while keeping the proportionality tables, answer choices, and y = kx practice intact.
