Identify triangles, quadrilaterals, pentagons, hexagons, circles, cubes, prisms, and pyramids.ĭescribe attributes & properties of two- and three-dimensional shapes.ĭraw shapes with specified attributes such as the number of angles or sides. Recognize that the size of the unit used affects the number of units required to measure an object.Įstimate and measure to compare lengths and express the difference in standard units. Measure lengths by selecting and using an appropriate tool.Īnalyze the results of measuring the same object with different units. Tell and write time to the nearest 5 minutes. Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing with unknowns in all positions.Įxpress even numbers as being composed of equal groups and write a number sentence to represent the number with 2 equal addends.Įxpress even numbers as pairings/groups of 2, and write a number sentence to represent the number using addends of 2.įind and represent the value of combinations of dollar bills, quarters, dimes, nickels, and pennies using $ and ¢ appropriately.įind combinations of coins that equal a given amount. Number Sentences, Equations & Inequalities Use the associative and commutative properties as strategies to add and subtract. Use the relationship between addition and subtraction to solve problems. Partition circles and rectangles into two, three, or four equal shares.ĭescribe the shares using the words halves, thirds, fourths, and quarters and use the phrases half of, third of, fourth of, and a quarter of.ĭescribe the whole as two of, three of, or four of the sharesĭemonstrate that there are various ways to divide identical wholes into equal shares. Partition a rectangle into rows and columns of same-size squares and count to find the total number of squares. Write an equation to represent the total number of objects arranged in a rectangular array as a sum of equal addends. (Note: Fluency refers to accuracy and efficiency and does not equate to memorization.)Īdd and subtract within 1,000 and j ustify answers using concrete models, drawings, or symbols that convey strategies connected to place value understanding.įind the total number of objects arranged in a rectangular array with up to five rows and 5 columns. (Note: Fluency refers to accuracy and efficiency and does not equate to memorization.)įluency within 100: Use strategies based on place value (including composing and decomposing tens), properties of operations, and/or the relationship between addition and subtraction to demonstrate fluency with addition and subtraction within 100. Automaticity for basic facts is desired.įluency within 20 : Use mental strategies to demonstrate fluency with sums and differences (Sums within 20 and the starting point for subtraction problems within 20). Recall addition and subtraction fact strategies. Use number bonds to represent number combinations.Ĭompose and decompose multi-digit numbers. Use place value models, place value charts, and a 100 chart to represent numbers to 1,000.Įxpress numbers to 1000 in standard and word forms.Ĭalculate 10 or 100 more or less than a given number within 1,000 mentally without having to count. Group objects and numbers up to 1,000 into hundreds, tens, and ones. Understand that 100 can be thought of as 10 tens, called a 'hundred'. Use place-value models to create equivalent representations of numbers. Represent numbers to 1,000 on a number line.Ĭompare numbers to 1,000 using the symbols >, , < or =.ĭetermine if a set of objects has an odd or even number of members. Use concrete and pictorial models to create a set with a given number of objects (to 1,000). Relationships Between Numbers and Quantities Read and write numerals to 1.000 using number names, base-ten numerals and expanded form.Ĭount to 1,000 by 1’s, 10’s and 100’s starting with any number.Ĭount by 2’s to 100 starting with any even number.Ĭount by multiples of ones, tens and hundreds starting from various values.
