Numerical Expressions From My Own Numbers
Written by Adi Ackerman, Head Teacher
"Numerical Expressions From My Own Numbers" is written for 7th Grade (Ages 12-13), and it covers Common Core 7.NS.A.3. A 6th grader who is already steady on rational numbers can use it too, and an older student can use it as a short review.
7th grade math worksheet: write numerical expressions from eight of their own numbers, like hours slept and dollars spent, and find each value. Part of our mixed rational number operations collection. Aligned to Common Core standards.
How do I use this worksheet?
Use the decimals and fractions sheets first, then add grouping. The missing operations sheets work well as a short warm up, and the own numbers task works well as a take-home page.
What students will practice
- Students will list eight numbers from their own week, such as minutes read and glasses of water.
- Students will write an expression for each rule, using their own numbers.
- Students will find the value of each expression, including ones with negatives.

What does this worksheet teach?
⌄
Write numerical expressions from eight of their own numbers, like hours slept and dollars spent, and find each value. The directions on the page read: Write your own 8 numbers in the list. Then write one expression for each rule using your numbers, and write its value. Use the back of the page for your work.
Can I use this mixed rational number operations worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade rational numbers, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What is the order of operations with signed numbers?
⌄
Work inside parentheses first, then multiply and divide, then add and subtract. The same order holds for negatives, fractions and decimals. Rational Number Operations With Grouping practices all of it.
Do all the sheets have answer keys?
⌄
6 of the 7 do. Numerical Expressions From My Own Numbers has students use eight numbers from their own week, so there is no single answer to print.
What are the missing operations sheets?
⌄
Students write plus, minus, times or divide in each circle to make an equation true, such as 5.8 and negative 2.7 to make 8.5. There is one sheet with signed decimals and one with signed fractions.
