Get DEEPER Math learning from your students. Get them thinking.

Grades K-12

Worksheets and THINKING activities are organized by strand on the right side of the website.

There is a great worksheet called "Open Middle Worksheet" on the top right for kids to document their process for problem solving. It gives them up to 6 attempts and the ability to explain what they have learned and how they need to change their approach for the next attempt.

This site accompanies the book "Open Math" by Robert Kaplinsky, but you do NOT need the book to benefit from these excellent questions.

Click "Get Our Favorite Problems" to get started (you will need to enter your info.) or use the menu organized by grade and strand on the right side of the page.

Free webinars are also recorded and available for elementary and secondary teachers to help "rethink classwork"

Example Question - Grade 3 - How many numbers are there between 1 and 3? (great way to introduce fractions).
