In this set of addition and subtraction word problems students are encouraged to find their own way to solve the problems. This enables students to discover the strengths and weaknesses of different solution methods and to see how multiple methods all arrive at the same answer. Included with the problem set are tips for getting started, the solutions, a teacher resource page, and a printable student page.

This three-act math task utilizes videos and questioning to help students explore adding and subtracting money.

Open Middle tasks provide opportunities for student to approach a mathematical task using different strategies and representations. They can be used as a warm-up/closing activity, as a formative assessment, or to facilitate discourse and discussion and get insite into student thinking and problem solving. These tasks provide a great opportunity for student to engage with the Standards for Mathematical Practice.

This three-act math task utilizes videos and questioning to help students explore multiplication and division within 100.

This problem is designed to help young learners use the symbols plus, minus, multiplied by, divided by and equals to, meaningfully, in ten number statements. Students must drag two operational symbols to empty boxes to make a true statement. This problem also helps learners understand inverse operations and to look for alternate solutions. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, ideas for extension and support, printable worksheet.
