Grade 2: January Unit
 A Thousand, Patterns, and Arrays (@ 15 days)
 

Overview

January focuses on learning critical mathematics skills and includes lessons that use math language to explain and describe patterns, numbers to 1,000, beginning multiplication, strategies to solve math problems, and measuring in various ways. Second graders will experience math activities using shapes to identify fractional parts of a whole, explain the answers to math problems, and demonstrate the difference between adding and subtracting using manipulatives. Students will learn to create, extend, and explain patterns. Beginning multiplication will continue to explore number patterns in multiples and arrays. Students will choose appropriate units of measurement using standard and non-standard units, familiar objects as reference for measurement, and measure longer distances. Students will practice estimating and measuring the capacity of cups, pints, quarts, and gallons.

Standards

Enduring Understandings are 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.

  • Recognizing patterns helps us make sense of our world.

  • Geometry builds our world.

  • Estimation, measurement, and computation are vital math tools.

Essential Questions are 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?

  • What is a pattern?  Where do we find patterns?  What can patterns reveal?

  • What is geometry? How do we use geometry in our everyday lives? How does geometry build our world?

  • How is time a measurement?

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

Your second grader is learning the beginnings of challenging mathematics! You can help and support by asking your child to create patterns with you. Use a variety of household objects to build more elaborate patterns. Show your child how to line up similar objects in equal rows making a multiplication array. Point out how multiplication is repeated addition. Show fractional parts of a whole using candy, pizza, or cookies. Encourage your child to help you measure ingredients in cooking; liquids and dry ingredients, both. Tell each other simple addition and subtraction stories and have your child explain how they got their answer. These at home math activities are no cost, lots of fun, and give a tremendous return on your investment!
