*4th Grade Ohio's New Learning Standards for Mathematics
*Current content standards that we are addressing
*Standards that reinforce Math Fact Fluency in support of 4th Grade Learning Standards & will addressed all year
Students will be able to:
-fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
-multiply one-digit whole numbers by multiples of 10 in the range 10-90 (e.g., 9 × 80, 5 × 60) using strategies based on place value and properties of operations.
-recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. (4.NBT.1)
-read & write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, <, = symbols to record the results of comparisons. (4.NBT.2)
-use place value understanding to round multi-digit whole numbers to any place. (4.NBT.3)
-fluently add and subtract multi-digit whole numbers using the standard algorithm. (4.NBT.4)
-multiply a whole nmber of up to four digits by a one-digit whole number, and multiply two two digit numbers. (4.NBT.5)
-find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors. (4.NBT.6)
-interpret a multiplication equation as a comparison. (4.OA.1)
-multiply or divide to solve word problems involving multiplicative comparison. (4.OA.2)
-solve multi-step word problems posed with whole numbers & having whole number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. (4.OA.3)
-find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factors. Determinewhether a given whole number in the range 1-100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1-100 is prime or composite. (4.OA.4)
-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. (4.OA.5)
-explain why a fraction is equivalent to another fraction using visual models. (4.NF.1)
-compare two fractions with different numerators and different denominators (4.NF.2)
-understand addition and subtraction of fractions as joining and separating parts referring to the same whole; decompose a fraction into a sum of fractions with the same denominator in more than one way; add & subtract mixed numbers with like denominators; solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators. (4.NF.3)
-apply and extend previous understandings of multiplication to multiply a fraction by a whole number and solve word problems involving multiplication of a fraction by a whole number. (4.NF.4)
-express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 & 100. (4.NF.5)
-use decimal notation for fractions with denominators 10 or 100. (4.NF.6)
-compare two decimals to hundredths by reasoning about their size. (4.NF.7)
-know relative sizes of the metric measurement units within one system of units. Metric units include kilometer, meter, centimeter, millimeter, kilogram, gram, liter, milliliter and express a larger measurement unit in terms of a smaller unit. Record measurement conversions in a two-column table. (4.MD.1)
-Solve real-world problems involving money, time, and metric measurement. Using models, add & subtract money and express the answer in decimal notation. Using number lines, clocks, or other models, add and subtract intervals of time in hours and minutes. Add, subtract, and multiply whole numbers to solve metric measurement problems involving distances, liquid volumes, and masses of objects. (4.MD.2)
-develop efficient strategies to determine the area and perimeter of rectangles in real-world situations. (4.MD.3)
-display and interpret data in graphs - picture graphs, bar graphs, and line plots - to solve problems using numbers & operations for this grade. (4.MD.4)
-recognize angles as geometric shapes that are formed wherever two rays share a common endpoint; understand 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. (4.MD.5)
-measure angles in whole-number degrees using a protractor & sketch angles of specified measure. (4.MD.6)
-recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real-world and mathematical problems. (4.MD.7)
-draw points, lines, line segments, rays, angles - right, acute, obtuse - perpendiular & parallel lines. Identify these in two-dimensional figures. (4.G.1)
-classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines or the presence or absence of angles of a specified size. (4.G.2)
