Grade 3 Math Resources

1) Log into www.ixl.com/signin/klsd using username and password (example pretend student login is: username: jfisher22 and password: 284453Jf), click on the ‘State Standards’ tab, choose NY, and choose their grade level, click on the link as titled below.

OR

2) Directly click on a link below (this will be easier for students).  However, if clicking directly on the link below, this will take you to www.ixl.com the general website, not the URL specific to KLSD.  Therefore, if clicking directly on the link below there is a slightly different method of logging in.  Instead of simply using username to log in, student needs to enter username@klsd in the username field (example pretend student login is: username: jfisher22@klsd and password: 284453Jf).

Student MUST log in.  If student does not log in, then his/her responses to the math questions do not get logged, and the student will face a limit of only being able to answer 20 questions per day.  If the student logs in, then s/he can solve an unlimited number of problems.

Login box is at the top, towards the left.  Again, student MUST log in.  Even though they can solve problems without being logged in, they need to log in so that they don't face the 20 question limit and so that their progress in each module can be logged in the Reports tab of IXL (that's a tab on the top navigation bar of IXL).

Modules should be followed in consecutive order as listed below.

The following are modules in IXL.com that correspond with EngageNY’s 3rd grade Common Core Math module 1 http://www.engageny.org/resource/grade-3-mathematics-module-1

 Grade 3 Module 1: Properties of Multiplication and Division and Solving Problems with Units of 2–5 and 10

3.OA.1 Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each.

3.OA.2 Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each.

3.OA.6 Understand division as an unknown-factor problem.

3.OA.5 Apply properties of operations as strategies to multiply and divide.

3.OA.4 Determine the unknown whole number in a multiplication or division equation relating three whole numbers.

3.OA.7 Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.

3.OA.3 Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

3.OA.8 Solve two-step word problems using the four operations. 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.

 The following are modules in IXL.com that correspond with EngageNY’s 3rd grade Common Core Math module 2 http://www.engageny.org/resource/grade-3-mathematics-module-2

Grade 3 Module 2:  Place Value and Problem Solving with Units of Measure

3.NBT.2 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.

3.MD.1 Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.

3.MD.2 Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.

The following are modules in IXL.com that correspond with EngageNY’s 3rd grade Common Core Math module 3 http://www.engageny.org/resource/grade-3-mathematics-module-3

Grade 3 Module 3: Multiplication and Division with Units of 0, 1, 6–9, and Multiples of 10

3.NBT.3 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.
