 3.OA.A.4 I can find the missing number in a multiplication or division equation.

 3.OA.B.5 I can use the Commutative property of multiplication. (I know that if 6 x 4 = 24, then 4 x 6 = 24.)

 3.OA.B.5 I can use the Associative property of multiplication. (To figure out 3 x 5 x 2, I can multiply 3 x 5 = 15, then 15 x 2 = 30 OR multiply 5 x 2 = 10, then 3 x 10 = 30.)

 3.OA.B.5 I can use the Distributive property of multiplication. (To figure out 8 x 7, I can think of 8 x (5 + 2) which means (8 x 5) + (8 x 2) = 40 + 16 = 56.)

 3.OA.B.6 I can find the answer to a division problem by thinking of the missing factor in a multiplication problem. (I can figure out 32 ÷ 8 because I know that 8 x 4 = 32.)

 3.OA.C.7 I can multiply and divide within 100 easily and quickly because I know how multiplication and division are related.

 3.OA.D.8 I can solve two-step word problems that involve addition, subtraction, multiplication and division.

 3.OA.D.8 I can solve two-step word problems by writing an equation with a letter in place of the number I don't know.

 3.OA.D.8 I can use mental math to figure out if the answers to two-step word problems are reasonable.

 3.OA.D.9 I can find patterns in addition and multiplication tables and explain them using what I know about how numbers work.

 

“I Can” Do Math (Numbers & Operations in Base Ten) I can use what I know about place value and operations (+,-,x,÷) to solve problems with larger numbers.

 3.NBT.A.1 I can use place value to help me round numbers to the nearest 10 or 100.

 3.NBT.A.2 I can quickly and easily add and subtract numbers within 1000.

 3.NBT.A.3 I can multiply any one digit whole number by a multiple of 10 (6 x 90, 4 x 30). 

 

I Can” Do Math (Numbers & Operations - Fractions) I can understand fractions.

 3.NF.A.1 I can show and understand that fractions represent equal parts of a whole, where the top number is the part and the bottom number is the total number of parts in the whole.

 3.NF.A.2 I can understand a fraction as a number on the number line by showing fractions on a number line diagram.

 3.NF.A.2.A I can label fractions on a number line because I know the space between any two numbers on the number line can be thought of as a whole.

 3.NF.A.2.B I can show a fraction on a number line by marking off equal parts between two whole numbers.

 3.NF.A.3 I can understand how some different fractions can actually be equal.

 3.NF.A.3 I can compare fractions by reasoning about their size.

 3.NF.A.3.A I can understand two fractions as equivalent (equal) if they are the same size or at the same point on a number line.

 3.NF.A.3.B I can recognize and write simple equivalent (equal) fractions and explain why they are equal using words or models.

 3.NF.A.3.C I can show whole numbers as fractions. (3 = 3/1)

 3.NF.A.3.C I can recognize fractions that are equal to one whole. (1 = 4/4)

 3.NF.A.3.D I can compare two fractions with the same numerator (top number) or the same denominator (bottom number) by reasoning about their size. 

 3.NF.A.3.D I can understand that comparing two fractions is only reasonable if they refer to the same whole.

 3.NF.A.3.D I can compare fractions with the symbols >, =, < and prove my comparison by using models.

 

“I Can” Do Math (Measurement & Data) I can solve problems that involve measurement and estimation.

 3.MD.A.1 I can tell and write time to the nearest minute.

 3.MD.A.1 I can measure time in minutes.

 3.MD.A.1 I can solve telling time word problems by adding and subtracting minutes.

 3.MD.A.2 I can measure liquids and solids with grams (g), kilograms (kg) and liters (l).

 3.MD.A.2 I can use addition, subtraction, multiplication and division to solve word problems about mass or volume.

 

I can understand how information is shared using numbers.

 3.MD.B.3 I can make a picture or bar graph to show data and solve problems using the information from the graphs.

 3.MD.B.4 I can create a line plot from measurement data, where the measured objects have been measured to the nearest whole number, half or quarter.

 

I can understand area.

 3.MD.C.5 I can understand that one way to measure plane shapes is by the area they have.

 3.MD.C.5.A I can understand that a "unit square" is a square with side lengths of 1 unit and it is used to measure the area of plane shapes.

 3.MD.C.5.B I can cover a plane shape with square units to measure its area.

 3.MD.C.6 I can measure areas by counting unit squares (square cm, square m, square in, square ft.).

 3.MD.C.7 I can understand area by thinking about multiplication and addition.

? 3.MD.C.7.A I can find the area of a rectangle using square tiles and also by multiplying the two side lengths.

 3.MD.C.7.B I can solve real world problems about area using multiplication.

 3.MD.C.7.C I can use models to show that the area of a rectangle can be found by using the distributive property (side lengths and b+c is the sum of a x b and a x c).

 3.MD.C.7.D I can find the area of a shape by breaking it down into smaller shapes and then adding those areas to find the total area.

I can understand perimeter.

 3.MD.D.8 I can solve real world math problems using what I know about how to find the perimeter of shapes.

“I Can” Do Math (Geometry) I can understand shapes better by using what I notice about them.

 3.G.A.1 I can place shapes into categories depending upon their attributes (parts).

 3.G.A.1 I can name a category of many shapes by looking at their attributes (parts).

 3.G.A.1 I can recognize and draw quadrilaterals (shapes with four sides) including rhombuses, rectangles and squares.

 3.G.A.2 I can divide shapes into parts with equal areas and show those areas as fractions.
