This worksheet gets students to use Spanish numbers for a purpose: figuring out the patterns. They must read the Spanish numbers and fill in the gaps in the patterns. Be sure to ask your students to explain their reasoning. Support the core in your language classroom by using these math patterns. I have used this successfully with students from 6th grade up to high school Spanish 1. The patterns involve basic addition/multiplication skills, using numbers from 0-100. Then students create their own patterns (in Spanish). Includes answer key.
