Mr. Von Osten, Fourth Grade

Welcome to Mr. Von Osten's Fourth Grade Class.  

It's hard to believe the end of the 2017-2018 School Year is almost here.  We have completed all the PARCC testing and we are winding down in our classroom.  This is my final year in a 31 year career as a teacher.  I will be retiring from Sandia Vista Elementary and RRPS May 24th.  I can honestly say, each day has been a learning experience and an adventure.  I sincerely hope the best for all future endeavors for all students, teachers, staff, parents and guardians here at SVE and Rio Rancho.


We are continuing with the ReadyGEN program.  In Unit 3, readers understand that different types of texts can be used to analyze similar topics and ideas. Writers understand that evidence can be drawn from both literary and informational texts to state and support opinions about a topic.  Learners understand that science is a newer method of explaining natural phenomena. For our Performance-Based Assessment, students will analyze two of the texts they have read in this module-Earthquakes and Quake!- and state and support an opinion about which text more effectively portrays the impact of earthquakes on human beings.

We are creating classroom groups in Reading/ELA to maximize time and focus on our students' needs.

Fraction Equivalence, Ordering,and Operations

Module 6 - Decimal Fractions       This 20 - day module gives students their first opportunity to explore decimal numbers via their relationship to decimal fractions, expressing a given quantity in both fraction and decimal forms.  Utilizing the understanding of fractions developed throughout Module 5, students apply the same reasoning to decimals, building a solid foundation for Grade 5 work with decimal operations.
