The "Multiplication Challenge" is something I do with my students each year. It consists of 20 "levels" (worksheets) of multiplication problems that get progressively harder each time. Each level contains 4-6 problems organized clearly and with plenty of open work space. In my classroom, students complete a level and move on to the next one when they get 100%. This allows me to monitor each student's progress and differentiate their practice. It also helps students to feel successful and build off of the skills they practiced previously. These worksheets can also be given as homework, used for review, or even used as assessments or timed-tests.
