PUZZLE MATH: Discovering Calculus By Roxanne Eckenrode
eBook (PDF): $22.00
This 22-page book is a first of its kind, providing a very active introduction to Calculus with discovery-style instruction and nine student centered decoder-style worksheets. Students are motivated... More > both by the instantaneous feedback and their inevitable success! Teachers love the improvement in comprehension as well as the ease of grading self-checking materials! Students investigate slope and average velocity to form a concept of instantaneous velocity expressed first as limits as x approaches a and then as h approaches 0. Next they derive the power rule, including using expressions with irrational constants, negative powers, roots, etc. Then they build to using the power rule when the base is a linear expression. They informally experience the chain rule and then move to more formal representations. Finally, they are introduced to the product rule, which serves as template for learning additional rules more formally.< Less

In this free algebra decoder worksheet students solve 2-step equations and then match their answers to parts of a secret message. Students are reinforced by immediate feedback which is excellent for... More > both learning and motivation. If teachers require students to show work, they reduce much grading overhead, because a correctly decoded message with work shown indicates the student has performed the standard. Whether students are working with Core Curriculum State Standards also known as Core Standards or with an individual state or countries' standards, solving equations is definitely a required skill. Finally, students can be taught some of the fundamentals of equation-solving even ahead of the typical prerequisite of performing operations with negative numbers.< Less

While having fun decoding a secret message... More > (and getting immediate, satisfying feedback) young students will complete simple addition problems. (A secondary goal of the worksheet for some students is to use inductive reasoning to notice that when an odd number and an even number are added, the answer is odd. Accordingly, when two odds or two evens are added, the answer is even.)

eBook (PDF): $2.99
Use these flashcards to practice the times tables (2s through 9s) with someone learning to memorize multiplication facts, first forward and then backward. Show the 'questions' like 8x6 in a random... More > order and put the student's 'misses' in one pile and the ones s/he gets correct in another. The student 'keeps' the ones s/he gets correct, and the questioner 'keeps' the misses in a separate pile to ask again after the initial pile has been gone through. Then the questioner mixes up the misses and re-asks them to the student. This process repeats until the student gets them all correct. Two pages of 'questions' and 'answers' are also included so that the student can view products like "24" and give their factors like "6x4" AND "8x3". It is important that students have immediate recall of these facts in both directions, 'forward' and 'backward'.< Less
