Fluently add and subtract multi-digit whole numbers using the standard algorithm. Grade 4 Arkansas 4. Use this principle to recognize and generate equivalent fractions. Recognize that comparisons are valid only when the two fractions refer to the same whole.
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, recording each decomposition by an equation.
Add and subtract mixed numbers with like denominators, e. Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.
Solve word problems involving multiplication of a fraction by a whole number, e. Between what two whole numbers does your answer lie? For example, rewrite 0.
Recognize that comparisons are valid only when the two decimals refer to the same whole. Represent verbal statements of multiplicative comparisons as multiplication equations.
Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1 — is a multiple of a given one-digit number. Determine whether a given whole number in the range 1 - is prime or composite. 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. Grade 4 Arkansas 5.
Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond e.
Grade 5 Arkansas 5.Triangle Congruence Worksheet #1 For each pair of triangles, tell which postulates, if any, make the triangles congruent.
O I can write a congruency statement representing two congruent polygons 1. Write a congruency statement for the two triangles at right.
Prove triangles congruent using the definition of congruence. If two geometric figures have exactly the same shape and size, they are congruent. Un two congruent polygons, all of the parts of one polygon are congruent to the corresponding parts or matching parts of the other polygon.
Practice B Congruence LESSON Write a congruence statement for each pair of polygons. In the figure, triangle PRT triangle FJH. 5. Find a. 6. Find b. 7. Find c. 8. Find x. 9.
