Skip counting (memorizing the multiples) is necessary for understanding and memorizing multiplication. These posters can be used in many ways in math centers, tutoring sessions, or for home practice: 1) Puzzles - Print on cardstock and cut apart the strips. Store each puzzle in an envelope. 2) Write and Wipe Off Cards: Print on cardstock and laminate. Students can write the facts that use the numeral as the answer or copy the multiples. 3) Posters for reference.
