Grade 2: December Unit
Math Words and Problems (@15 days)


Overview

View the video introduction. (Adding and Subtracting) December focuses on learning critical mathematics skills and includes lessons on using math language to explain the answers to math problems, and to demonstrate the difference between addition and subtraction. Students will understand more math vocabulary and practical uses of problem solving words and strategies and how to explain their mathematics thinking and processing.

Enduring Understandings - important ideas that students should carry with them years beyond the instruction received this year.

  • We need number sense and math words to communicate reasoning and to find reasonable solutions.

  • Estimation and computation are vital math tools.

Essential Questions - the most important “big picture” questions students should be able to answer after completing learning activities.

  • Why is it important to learn math words? 

  • How does having a sense of number help us find solutions and understand if our solutions are accurate?

CSAP Tested Standards  Highest Frequency High Frequency Other Standards and E-Skills

 Highest Frequency = the timing, intensity and level of accountability is extremely high because mastery of these skills will must be demonstrated at this grade level.
 High Frequency = the timing, intensity and level of accountability is high because mastery of these skills is expected at this grade level.
 Other Standards and E-Skills = the timing, intensity, and level of mastery are not urgent. It should be introduced during this time so students can experience the concept and return in future quarters to strive towards mastery.

Parents

You can help your second grader as he/she continues to learn more sophisticated mathematics in quarter 2 by helping with frequent practice of the concept of 10. Understanding the different combinations that can be used to make 10 is critical to number sense, place value, and higher level mathematics. Use common items around the house for this activity. Tell simple math stories that involve adding or subtracting small numbers, then have your child show you with objects like beans or buttons. Have your child tell you about their thinking and how they got the answer.  Do this often for awesome results!
