## Patterns
1/30/2015
Unit Name: PatternsCommon Core State Standards:4.OA.5 Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in a rule itself. Essential Vocabulary:· Pattern (number or shape) · Pattern rule Unit Overview:In this unit, students will apply their understanding of patterns with numbers and shapes from previous grades. In addition, this unit builds upon students’ understanding of multiples and factors in order for students to see the patterns and form a rule. Strategies/Skills:Students will build on their understanding of multiples, factors, and geometry to make sense of patterns. They are expected to use a variety of models to support their reasoning about numbers. · Function Table (vertical table/t-chart) · Number Line Video Support:Video support can be found on LearnZillion. · http://learnzillion.com o Find the rule for a function machine using a vertical table https://learnzillion.com/student/lessons/790-find-the-rule-for-a-function-machine-using-a-vertical-table o Understand repeating patterns https://learnzillion.com/student/lessons/791-understand-repeating-patterns o Find missing elements in growing patterns https://learnzillion.com/student/lessons/791-understand-repeating-patterns o Find the 9th shape for a geometric pattern using a table https://learnzillion.com/student/lessons/793-find-the-9th-shape-for-a-geometric-pattern-using-a-table o Determine the rule in patterns that decrease https://learnzillion.com/student/lessons/794-determine-the-rule-in-patterns-that-decrease o Using a table to find the rule for a geometric triangle pattern https://learnzillion.com/student/lessons/795-using-a-table-to-find-the-rule-for-a-geometric-triangle-pattern o Extend a fraction pattern using a number line https://learnzillion.com/student/lessons/796-extend-a-fraction-pattern-using-a-number-line o Generate a pattern sequence using a t-chart https://learnzillion.com/student/lessons/797-generate-a-pattern-sequence-using-a-t-chart o Find the missing inputs for a function machine using a vertical table https://learnzillion.com/student/lessons/798-find-the-missing-inputs-for-a-function-machine-using-a-vertical-table

## Area & Perimeter
1/20/2015
We will begin our next unit of study in math soon. The information below will serve as an overview of the unit as you work to support your child at home. If you have any questions, please feel free to contact me. I appreciate your on-going support.
Unit Name:Area and PerimeterCommon Core State Standards:4.MD.3 Apply the area and perimeter formulas for rectangles in real world and mathematical problems.Essential Vocabulary:· multiplication/multiply · area · array · square unit · product · perimeter · length · width Unit Overview:In this unit, students will apply their understanding of area and perimeter of rectangles from 3rdgrade to help them explore the understanding of the abstract formula A = l x w. In addition, students will generate and discuss the different pros and cons for the formulas for perimeter such as: P = 2l + 2w and P = 2(l + w). The first formula has an additional step compared to the second formula with multiplying the length by two, multiplying the width by two and then adding both together. The second formula has the length and width added together and then multiplying it by two. *Apply understanding to formula does not mean write down a memorized formula and put in known values. Students do not need to do this until 6th grade.Strategies/Skills:Students will build on their understanding of area and perimeter to make sense of the standard algorithms. They are expected to use a variety of models to support their reasoning about numbers. · Rectangular Section/Arrays · Base Ten blocks · Area Model Video Support:Video support can be found on LearnZillion. · http://learnzillion.com o Use area models to find the area of rectangles https://learnzillion.com/student/lessons/2374-use-area-models-to-find-the-area-of-rectangles o Find the area of a rectangle using the standard formula https://learnzillion.com/student/lessons/2535-find-the-area-of-a-rectangle-using-the-standard-formula o Find missing side lengths using the formula for area https://learnzillion.com/student/lessons/2425-find-missing-side-lengths-using-the-formula-for-area o Find the perimeter of a rectangle using area model https://learnzillion.com/student/lessons/2942-find-the-perimeter-of-a-rectangle-using-an-area-model o Find perimeter using the standard formula https://learnzillion.com/student/lessons/3047-find-perimeter-using-the-standard-formula o Find missing side lengths using the formula for perimeter https://learnzillion.com/student/lessons/3048-find-missing-side-lengths-using-the-formula-for-perimeter ## 2D Figures & Line Symmetry

Unit Name:2D FiguresCommon Core State Standards:4.G.2 Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of a specified size. Recognize right triangles as a category, and identify right angles. Essential Vocabulary:· quadrilateral · isosceles trapezoid · trapezoid · rhombus · parallelogram · rectangle · square · right triangle two-dimensional · right · obtuse · acute · attributes · parallel · perpendicular · congruent · equilateral · isosceles · scalene · kite Unit Overview:In this unit, students will build upon their understanding of identifying various shapes through attributes. In this unit students will focus on identifying parallel lines and perpendicular lines while identifying the angles used from the previous units: acute, obtuse, and right. Students will investigate the concept of “same size and same shape”; however, the concept of congruence and similarity do not appear until middle school.Strategies/Skills:Students will build on their understanding of geometric shapes and go further with identifying and measuring angles.

Identifying line-symmetric figures and draw lines of symmetry.Essential Vocabulary:· symmetry · line of symmetry · regular polygons · non-regular polygons · midpoint · vertex · two-dimensional Unit Overview:In this unit, students will learn about symmetry and line of symmetry for the first time. Students have explored dividing shapes into equal pieces since 1st grade. Now students will build upon this concept with symmetry. This concept also will help students with the numeric form of symmetry in the commutative property.
