Current Unit: Decimals

4.NF.6Use decimal notation for fractions with denominators 10 or 100.

*For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram*.

4.NF.7Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole.

4.NF.1 Explain why a fraction is still the same size if I multiply both the numerator and denominator by the same number. I can use this understanding to make equivalent fractions.

4.NF.2 I can compare two fractions with different numerators and different denominators by creating common numerators or denominators. I can compare two fractions with different numerators and different denominators by using a benchmark fraction. I can write my answers to fraction comparison word problems

using the symbols <, >, and =.

4.NF.3 I can add and subtract mixed numbers with like denominators; solve word problems involving addition and subtraction of fractions; and use visual models and fraction equations to represent the problem.

4.NF.4 Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.

Patterns

**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 the rule itself.**

*For example, given the rule "Add 3" and the starting number 1, generate*

*terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.*

**Circles, Lines & Angles**

__I can :__Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

__I can:__Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:

__I can:__Recognize An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a "one-degree angle," and can be used to measure angles.

__I can__: Recognize An angle that turns through n one-degree angles is said to have an angle measure of n degrees.

Multiplicative Comparisons

4.OA.1 I CAN: Understand a multiplication equation as a comparison, (Interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5.)

4.OA.2 I CAN: Multiply or divide to solve word problems involving multiplicative comparison (by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.)
