"Find the Hidden Equations: Jumbled Up Addition, Subtraction, and Multiplication Problems" is a great worksheet for students to practice their math facts and mental math skills.

Each worksheet features three different rectangles that are filled with a jumble of numbers. Some of those numbers are included in a math problem, like 8 + 2 or 8 x 6. The individual numbers floating around are possible answers to those equations, but not all the equations have answers, and not all the individual numbers are answers to one of the equations. Students have to find the two complete equations in each box and write them down below.

Lower grade-level worksheets focus on single-digit addition and subtraction problems with only a few numbers and equations floating around in each box. The difficulty level rises with each grade level. Higher-level problems include double-digit addition, subtraction, and multiplication problems.

As students become familiar with solving equations, it's easy for them to fall into a routine of working out the problem on paper. You can encourage problem-solving, critical thinking, and mental math skills if you present math problems in new ways.

Students could draw a line from an equation to its answer on the other side of the page, or they could find two equations and their matching answers in a jumble of numbers before writing the equations down. You can add an extra challenge by including equations and numbers that don't have a match. Problems can reflect what students are currently working on in class, whether it's addition, subtraction, multiplication, or division. Young students can focus on single-digit numbers and math facts, while older students can work on their mental math skills when solving double-digit equations.
