Common Core Standard: 7.G.B.4 In part one, I provided some Sticky Math Triads to put the process before students and teachers. While I struggled there to provide visual representations, I believe I have accomplished the goal here as we examine the resulting...

Common Core Standard: 7.G.B.4 I have to confess that while I have done a lot of conceptual work with students around circumference and area of a circle (see some of it by checking out my blogposts on each subject), I have not done much to tackle the latter part of...

Common Core Standard: 7.G.B.4 If area is defined as the number of unit squares that cover the surface of a closed figure, then how does this apply to a circle? Can we remember the abstract formula for area of a circle better by understanding where it comes from...

Common Core Standard: 7.G.B.4 These Sticky Math activities can each stand alone; however, each of these blogposts suggests how you might put them together to form a lesson. You can always adapt them to suit your needs. This Sticky Math Lesson helps build fluency from...

Common Core Standards: 8.NS.A.2 . Disclaimer: This post includes data from estimating square roots, but focuses on the concept of a square root. More on how to estimate square roots in a future blog post. I was working with a teacher who had just given a Smarter...

Common Core Standard: 3.OA.B.5 A week’s’ worth of warm ups or a single lesson; the choice is yours. If you need to revisit for conceptual, interleaved practice to build fluency and retention, then use this as a week of warmups. Alternatively, you could use...

1.OA.C.6 The Sticky Math Triad below asks for students to make connections between representations while beginning to explore the Commutative Property. By asking students to create additional equivalent representations, students may choose to find the sum by counting...
