10 number puzzles requiring students to think outside the box.
Low floor, high ceiling worksheet activities to encourage love of math and number connections.
This resource contains 10 task cards with one problem each or 5 worksheets with 2 problems each. Each problem has a “goal number” and 8 numbers to play with. You can use each number up to one time with any operation(s), but you do not need to use each number every time. This resource is available in both color and black and white. It is available in task card format and in worksheet format. There is an answer key included with at least 15 possible ways of solving each puzzle. However, there are some answers that you and your students may discover that aren’t included on the answer key.
Because of the openness of these problems, you can use the same ones more than once with your students! I hope your students enjoy solving these puzzles as much as my students do!
This resource can be used as an early-finisher task, as part of stations, as a number talk, as in class work or as homework. It can be used to open discussions aligned to 5.OA.A.1 and 5.OA.A.2 and the properties of mathematics.
Each puzzle has at least one solution that any student should be able to find, making it perfect for classrooms that have a wide range of student ability levels. The puzzles also have many complex solutions. Encourage higher students to find at least 5 solutions or to find a way to incorporate every number or every operation into their different solutions. Encourage students to find solutions that require parentheses or solutions that incorporate as many of the numbers as they possibly can.There are so many different ways to use this resource and to encourage your students’ problem solving and operational skills with it!
