These two worksheets are on solving proportions. One has students solve proportions equations, and the other has students set up and solve proportions equations to solve word problems. The secret... More > decoder format allows students to receive immediate feedback and reduces overhead for teachers too. Students who used these worksheets reported that they helped to practice the concepts and that they were enjoyable to complete.< Less
This packet includes two one-page math decoder worksheets. Students compare prices and savings in various real-world contexts. For example, students decide whether it would be more cost effective... More > to buy eight items or one dozen, and they examine savings when one subscribes instead of buying individual publications at the store. Answers correspond with code items, so students get immediate feedback. Teachers find less overhead when grading, accordingly.< Less
In this 15-page collection of self-checking decoder-style multiple choice math worksheets for middle school students, learners get immediate feedback as they answer questions on a variety of math... More > topics. They will have fun revealing secret messages as they prepare for standardized tests and for cumulative tests such as midterms and final examinations, especially for seventh and eighth graders. These materials have been used successfully by teachers with real middle school students who reported upon them favorably. Topics include probability, rate, signed numbers, decimals, fractions, all operations, graphing, shapes, percent, equations, expressions, and much, much more!< 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
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 5-page packet students read and discover about the angles formed when a pair of lines intersect and when a transversal cuts a pair of parallel lines. Students intuitively learn about the... More > names of the pairs of angles formed and about those angles' measures. On the 5th page students put their new skills to the test while they receive immediate feedback completing a decoder-style worksheet on which they will both identify angles' names and measures.< Less
