Start your year with these once a week multi-step math problems. This is a sample of the word problems included in my Kiss Your Brain Math Challenges 1-4. Using multi-step word problems allows students to apply their math skills at a higher level and has significantly increased my students' ability to think critically and problem solve. They can be used for enrichment, test prep, assessment or a weekly math challenge. Geared toward 3rd grade standards but can be used as 2nd grade enrichment or 4th grade remediation.
