Meet Mr. Larry

Mr. Larry (as his students call him) entered teaching after a successful career as a restaurant owner in La Crosse. Mr. Larry created, and continues to operate Pizza Doctors in downtown La Crosse. However it was time spent volunteering in his own children’s elementary classrooms that convinced Mr. Larry that he should return to school and become a teacher. Mr. Larry graduated from Viterbo University with a degree in education in 2004. He started as a pre-school teacher at Franklin and has been at Franklin, Roosevelt and Northside. In addition to pre-school, Mr. Larry has taught kindergarten, 2nd and now 4th grades.

 

When Mr. Larry is not teaching or working at Pizza Doctors, he spends his time relaxing and playing with his dogs at the family cabin in northern Wisconsin.

Math Word Problem Strategies

and Practice

 

Word problems (or story problems) are the most difficult concept for fourth grade students to grasp. Sometimes it’s the vocabulary, but many times it’s just understanding how to set up a problem and what operation(s) to use. These websites offer strategies and practice to help students become story problem masters.
