What Educators Are Saying

  • We have a lot of social/emotional needs in my school so I love that Exemplars helps students learn to work together, share ideas, critique each other in a meaningful way, while also developing some pretty awesome critical thinking and reasoning skills ... I feel like I could go on and on about how much I love using Exemplars.

    Tess McCafferty, Teacher, OH

    If I think about all the strategies teachers have used to try to improve student achievement in math, the Exemplars program was the most powerful.

    Diane Ullman, Assistant Superintendent, CT

    I am determined to improve in math. The years I used Exemplars with fidelity my scores jumped tremendously; teachers actually assessed and enjoyed the art of teaching and students were always self assessing.

  • Exemplars tasks have proven to be engaging for our Title I students. Use of the student-scoring rubric helps students understand exactly what is expected of them as they solve problems. This knowledge carries over to other mathematics tasks.

    I was amazed to see the differentiation and the student examples. So many times we see the problems, but not actual student work. Thank you so much for allowing me to see student work and the DIFFERENT ideas so that it's not me creating "mini mes" but showing students how to arrive at the answer in many different ways!

    C. Kendrick, Teacher, IL

    This is an excellent resource! Thanks for making it available. Exemplars are a wonderful tool for our highly capable math students. They encourage them to show their work, explain their thinking, and label their answers.

  • I really loved Exemplars. They really challenge my mind. Exemplars really helped me in math... At the beginning of Exemplars I was never good, because I was an Apprentice, now I'm really good...I learned from Exemplars that there are so many different kinds of math, for example, adding, multiplication, division and subtraction.

    I am a special education teacher, and I have been using the math Exemplars with my students. They enjoy doing them and have actually asked to do them. I have noticed that with each problem we solve more and more students are trying to stretch their thinking so they can become 'Experts'.

    J. Reardon, Special Education Teacher

    I have really enjoyed using Exemplars. Teaching students how to become better problem solvers has been easier and the students have a more concrete format in which to follow. The rubric is very user friendly. It has really allowed my high-achievers to reach a new level. Problem solving is usually a weakness for them, because they only want to get the right answer... this has opened their eyes to a new way to express themselves mathematically.
