## UbD Curriculum Unit

**Target Students:** This course unit is designed for students in their practicum placement in their algebra course title in mathematics for 10th grade students. The unit is on algebraic expressions.

**Course statement**: Pre-Algebra: upon the course completion the students will be able to; understand relations and functions, solve word problems using equations, solve quadratic equations, operate polynomial equations, solve inequalities using graphs and other methods, solve linear equations, evaluate algebraic expressions, understand word problems, and exponents and roots. https://essayharbour.info/2021/05/31/w%e2%80%8c%e2%80%8d%e2%80%8d%e2%80%8d%e2%80%8c%e2%80%8d%e2%80%8d%e2%80%8c%e2%80%8c%e2%80%8d%e2%80%8d%e2%80%8d%e2%80%8c%e2%80%8d%e2%80%8d%e2%80%8d%e2%80%8d%e2%80%8c%e2%80%8d%e2%80%8drite-a-paper-disc-2/

**Unit statement**: The unit is on algebraic expressions; it incorporates simplifying and evaluating algebraic and numeric expressions. The unit will build foundation on patterns and operations of decimals, integers and fractions.

Lesson Plan

In teaching Algebraic expressions for grade 10 mathematics it will require 10 lesson units that include; real number systems, rational and irrational numbers, rounding off, estimating surds, products, factorization, simplification of fractions, summary, end of chapter exercises and practicing the chapter. The hunter’s model identifies that there are eight elements used by teachers when planning and presenting their lessons (Owen, 2015). The elements are; anticipatory set, objective and purpose, input, modeling, checking for understanding, guided practice, independent practice and closure.

**LessonObjectivesMaterialsDevelopmentPractice**Day 1:

Real number systems

Use of whole numbers, real numbers and integersWork sheets and pre-printed notes.

Handouts

The students will watch the teacher working out different examples on real number system. The students will be guided through at least three practice problems. Day 2:

Rational and irrational numbers https://essaypandit.com/assignment-7how-technological-advancements-and-changes-may-affect-how-we-can-wo/

Understanding rational and irrational numbers, using decimal numbers, converting terminating decimals into rational numbers, converting recurring decimals into rational numbers.Mini-white board, poster paper and scrap paper, hint sheets and calculatorStudents attempt tasks individually. Then teacher makes the introduction. Then the students attempt the tasks in groups. Students handed practice problems and exchange sheets for marking. Day 3 :

Rounding off

Use the quickest way to approximate a number by rounding off a number to a given number of decimal placesPre-printed numbers and number cardsStudents will be required to round off a number to the nearest tens, hundreds and thousands.The students will be guided through at least three practice problems.Day 4: Estimating surdslook at surds of the form a√n
