MP1 Make sense of problems and persevere in solving them. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals.
Use place value understanding and properties of operations to add and subtract. Add up to four two-digit numbers using strategies based on place value and properties of operations.
Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.
Mentally add 10 or to a given number —, and mentally subtract 10 or from a given number — Explain why addition and subtraction strategies work, using place value and the properties of operations.
Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes. Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.
Measure and estimate lengths in standard units. Estimate lengths using units of inches, feet, centimeters, and meters. Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.
Use addition and subtraction within to solve word problems involving lengths that are given in the same units, e.
Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, …, and represent whole-number sums and differences within on a number line diagram. Tell and write time from analog and digital clocks to the nearest five minutes, using a.
If you have 2 dimes and 3 pennies, how many cents do you have? Common Core State Standards: Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object.
Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units. Draw a picture graph and a bar graph with single-unit scale to represent a data set with up to four categories.
Solve simple put-together, take-apart, and compare problems 1 using information presented in a bar graph. Geometry Common Core State Standards: Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.
Identify triangles quadrilaterals, pentagons, hexagons, and cubes. Partition a rectangle into rows and columns of same-size squares and count to find the total number of them. Recognize that equal shares of identical wholes need not have the same shape.Study Island is a leading academic software provider of standards-based assessment, instruction, and test preparation e-learning programs.

Common Core State Standards Related to Homophones. leslutinsduphoenix.com Demonstrate command of the conventions of standard English grammar and usage when writing or speaking: Correctly use frequently confused words (e.g., to, too, two; there, their).
Most states have, or are developing, tests to assess their students’ proficiency in state frameworks of curriculum. Many of these states are including students with limited English proficiency in this assessment process, but a significant number of LEP students have difficulty passing these standardized tests.
