The Khan Academy is a free website that includes instruction and guided practice.
The Khan Academy has many, many topics in algebra and other areas of mathematics, science, etc. The practice sections relevant to the Keystone Algebra 1 test in the Khan Academy LEARN center are organized below. Each link contains interactive practice, hints, worked out solutions and links to video instruction if needed (The video links are on the lower right hand side of the page.)
After logging in, select an assessment area that needs improvment. Use the links on this page to select the practice. When moving to a new topic, return to this page to pick the next practice area.
Module 1
1.1 Operations
(Please note. Module 1.1 Operations contains the greatest number of topics to master but is not weighted more heavily than the other assessment areas. For this reason, it makes sense to focus on 1.1 AFTER remediating the other five assessment anchors first.)
