Collaborative learners will see the geometric addition of functions by graphing the sum of two graphed curves on the same coordinate plane. This task then naturally flows into giving learners the algebraic representation of the curves...

Common Core is all about getting your learners to open their minds and think about the why and how. This problem has them thinking about unknown numbers and their relationship with one another when we round and...

Wonder how many pieces of candy a teacher can eat. Pupils watch a video of candy in a bowl as some candy is removed to be eaten and others are added. Learners devise questions about the situation along with estimated solutions. Scholars...

Time for more candy! Learners view a video of a candy bowl where some of the candy is removed and more placed back. Scholars come up with questions about the scenario to answer and request additional information from the teacher. At the...

In this activity, students will round fractions and mixed numbers, and then use their rounding skills to estimate sums, differences, products, and quotients.

Problem solving will become a little easier when you understand the concepts of estimation and rounding. Explore how these concepts are used in mathematics and real world applications. Detailed examples and links to related games...
