Math
Cherry Creek School District uses Bridges in Mathematics. I will also supplement that curriculum with a variety of math activities, websites, and resources. Each unit will begin with a pre-test and end with a post-test. This will provide valuable information for differentiation among our math activities and math centers.
In our first unit, we will be reviewing basic addition and subtraction strategies; as well as expanding to two and three digit problems. We will continue to "explain our thinking" and use a variety of strategies. Story problems will be a big focus in this unit as well.
In the next unit, we will continue with story problems, adding and subtracting one, two, and three-digit numbers, rounding to the nearest tens and hundreds, and place value concepts. Algebraic concepts will be introduced within the story-problems.
Our third unit focuses on multiplication and story-problems with graphs. Students will explore multiplication through arrays, number lines, ratio tables, and the multiplication table. The story-problems in this unit include graphs and multiple operations.
Our fourth unit explores measurement and introduces fractions. Time, mass, volume, and linear measurement will be included, as well as problem-solving using a variety of measurement tools. Students will use different models to build, compare, and investigate the relationship among unit and common fractions.
Unit 5 returns to multiplication, especially as it relates to division. Story problems are a major focus as students connect everyday life to division. As they solve problems, students will use sharing and grouping to build a deeper understanding of multiplication and division.
Unit 6 will provide an introduction to geometry and the vocabulary of geometry. Students will describe and classify two-dimensional shapes, especially quadrilaterals. Students will also calculate area and perimeter. Fractions as parts of a whole shape will be explored in this unit as well.
In Unit 7, we will extend our thinking about multiplication and fractions. Students will develop and use strategies for multiplying by 11 and 12, as well as multiplying single-digit numbers by two-digit numbers. Solving story-problems involving fractions will be an important part of this unit as well.
