**MATHEMATICS****Instruction in mathematics is delivered in a contextual fashion in many of our career and technical education programs. Using the collaborative teaching model, as upheld by the Michigan Department of Education, highly-qualified math teachers work together with the technical instructors to deliver instruction, aligned to the technical curricula's segments and standards and Common Core State Standards in mathematics. Students, attending TBAISD Career-Tech Center, have the opportunity to earn academic credit in Algebra II A and B, Geometry, and 4th Year Math.**

**MATH ESSENTIALS - Many students entering technical programs demonstrate that they do not possess basic math skills in the areas of adding, subtracting, multiplying, and dividing whole numbers, fractions and decimals, of converting fractions to decimals, and working with linear measurement. As a result, the math teachers work weekly with the students on these concepts until they are able to demonstrate mastery. Pre/post-tests are administered to students to measure their growth in these areas. Additionally, there is a Math Essentials Matter website, complete with activities, lessons, and videos that enable students to improve their skills in an online fashion.**

**CONSTRUCTION TRADES, ELECTRICAL OCCUPATIONS, SKILLED TRADES AND ALGEBRA II - This four day lesson was created by mathematics instructor, Karen Shoskey. Using ratios and scale with house plans is the main theme of the lesson. Day one consists of students taking a pretest to determine familiarity with ratios, introducing ratios and expressions, writing ratios in simplest form, and solving for unknown values. Once students master these concepts, they are asked to create a scale drawing of an area, find a house plan and determine the scale, and finally create their own scale drawing of a construction trades-related scale drawing.**

**CONSTRUCTION TRADES, ELECTRICAL OCCUPATIONS, SKILLED TRADES AND ALGEBRA IIB - In this activity, which was used with Construction Trades, Electrical Occupations, and Skilled Trades students who are enrolled in Algebra IIB, mathematics instructor, Deb Menchaca, introduces the students to the learning theory behind drawing ellipses in order to be able to create elliptical shapes for windows. Students have the opportunity to explore both the nail and string method, as well as the trammel method. Students are asked to relate the Algebra II B concepts that are embedded in this activity.**

**CULINARY ARTS AND FOURTH YEAR MATH - Created by mathematics instructor, Karen Shoskey, this lesson is used in the Culinary Arts program. It demonstrates how to calculate edible portion quantity as well as yield percentage of various food items. Students realize the importance of math when creating a recipes and developing menus.**

**GRAPHICS ARTS AND FOURTH YEAR MATH****-****This lesson was created by mathematics instructor, Karen Shoskey, for Graphics Arts. Students are given two d****ifferent print orders and asked to develop price quotes. Each quote involves four components: supplies, labor, additional costs and a profit mark-up. Students design the items (bookmarks and postcards), determine how many will fit on a page, and then calculate costs involved.**

**GRAPHIC ARTS AND FOURTH YEAR MATH****- This math project was created by mathematics instructor, Karen Shoskey, and Graphic Arts instructor, Julie Orr. This was a final math project that students selected in which they create a children's book, game, or short. For this project, they work independently to create one of the three outcomes that is used to teach a math concept, selecting a topic that was covered in the math portion of the program throughout the academic school year. Rubrics are included to evaluate the book, game, or short, making certain that the math objectives outlined in the project instructions are addressed.**

**PRECISION MACHINING TECHNOLOGY AND GEOMETRY- This lesson was developed by mathematics instructor, Joel Carpenter, for Precision Machining Technology. Joel created a short video demonstrating how to compute the sine of the angle for a gage block stack up. Gage blocks are used in machining to produce precision lengths. A wide variety of standard lengths can be created by stacking the blocks.**

**OWER EQUIPMENT TECHNOLOGY AND FOURTH YEAR MATH****-****This unit plan was created by mathematics instructor, Karen Shoskey. It covers electrical concepts used in Power Equipment Technology. Specifically, Ohm’s Law and how it relates to electrical current potential and resistance of both parallel and series circuits is the main focus of this unit. This file contains resources such as a PowerPoint review of Ohm’s Law and quiz and information and calculations of series and parallel circuits. Note taking guides are also included for students to use during lectures.**

**POWER EQUIPMENT TECHNOLOGY AND FOURTH YEAR MATH - Pi Day was developed by mathematics instructor, Karen Shoskey. Students used yarn to measure the circumference and diameter of an engine block and a cookie. After taking measurements, students calculated the ratio of the circumference to the diameter. Critical thinking skills are utilized to analyze results and determine of calculations are accurate. If not, they must troubleshoot for possible causes.**

**WELDING AND FOURTH YEAR MATH -****The lesson plan was developed by mathematics instructor, Deb Menchaca, for use in our Welding Program. In this lesson, the Welding Instructor, Rick Mathis, explains real world requirements to build a tank. Students learn the relevance of geometry in Welding as they learn how to find the volume of a tank. In a manner that minimizes waste, students are asked to recreate a tank on card stock paper, to scale, from a blueprint.**
