Frequently asked questions
Can I print the Equation Explorer?
No. It is the one activity on the site meant for the screen: terms are dragged across the equals sign, the number line animates, and answers are checked as they are typed. Every other worksheet here prints on one page.
What does moving a term across the equals sign mean?
An equation stays true as long as both sides change in the same way. Moving a term across flips its sign, so x + 7 = 12 becomes x = 12 − 7. Seeing the sign flip as it happens makes the rule concrete rather than memorised.
What age is it for?
Grades 2 and 3, roughly ages 7 to 9, once addition and subtraction within 100 are comfortable. It is usually a child's first sight of a letter standing for an unknown number.
