Using an Elevator to Evaluate Signed Number Expressions
Using the idea of an elevator moving up and down, students will be given a small set of rules to add and subtract signed integers. The idea behind the method of adding and subtracting signed integers offered in these lesson is that the number of rules that s

The objective of this lesson is to use combinations to solve KenKen puzzles. An early solution strategy is for students to guess and check and use logic-based elimination. This lesson builds on those strategies by having students systematically list all possible combinations within each cage, the darkly outlined sections of the puzzle.
Pre-K-2
In this lesson, students practice addition (subtraction optional) and deductive reasoning skills to solve KenKen puzzles.

This lesson is based on the MTLT article, “Inquiry + Math Workshop Model = Success!” by Tutita M. Casa, Kathryn O'Connor, and Emma Dearborne. The lesson demonstrates the use of a workshop model that engages students in developing strategies to solve an authentic multiplication task.3-5
This lesson is based on the MTLT article, “Playing with Fractions” by Juli K. Dixon, Treshonda Rutledge, Jennifer C. Caton, and Edward C. Nolan. In this lesson students model fractions with a fraction kit and reason about adding fractions with unlike denominators. 6-8
In this lesson, students will integrate science and math, exploring how neutralization reactions can help us understand that the sum of any number and its additive inverse is zero. 3-5
Based on an MTLT article, the authors implement a coordinated series of well-connected number talks that allow for students to make sense of a variety of strategies that provide “flexibility” in their mathematical reasoning when comparing fractions.
