Grade 2 Math Resources

To find these links in IXL, students need to either:

1) Log into www.ixl.com/signin/klsd using username and password (2nd grade students all have a password that is simply the letter “a”, lowercase), 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: a).

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 2nd grade Common Core Math module 1

Grade 2 Module 1: Sums and Differences to 20

2.OA.1 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, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

2.OA.2 Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.

2.NBT.5 Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

Grade 2 Module 2: Addition and Subtraction of Length Units

2.MD.1 Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.

2.MD.3 Estimate lengths using units of inches, feet, centimeters, and meters.

2.MD.2 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.

2.MD.4 Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.

2.MD.5 Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem.

2.MD.6 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 100 on a number line diagram.

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

This module covers Place Value, Counting, and Comparison of Numbers to 1000.

 2.NBT.1 Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:

2.NBT.2 Count within 1000; skip-count by 5s, 10s, and 100s.

2.NBT.3 Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.

2.NBT.1.a 100 can be thought of as a bundle of ten tens - called a "hundred."

2.NBT.4 Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.
