## 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
