Grade 2: February Unit
Fractions, Measurement, and Communication (@ 20 days)

Overview
 View the video introduction. (Fraction Addition and Subtraction, or Break it Up) February focuses on learning critical mathematics skills and includes lessons that use math language to identify fractions, choose appropriate units of measure, measure with different units, and estimate with liquid measurements. Students will learn to explain their answers to math problems, name the difference between addition and subtraction, add money with a calculator, and use different strategies to solve math problems. Second graders will experience math activities using shapes to identify fractional parts of a whole, communicate the answers to math problems, and demonstrate the difference between adding and subtracting using manipulatives. 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 longer distances to measure. Students will practice estimating and measuring the capacity of cups, pints, quarts, and gallons.

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

  • In order to communicate solutions to problems, we must be able to understand and use the language of math.

  • A sense of number is necessary to communicate mathematical reasoning and to find reasonable solutions.

  • Numbers can be represented, ordered, and communicated in many different forms.

  • Recognizing patterns helps us make sense of our world

  • Graphics are tools used to clarify data.

  • Interpreting data displays helps us make sense of information.

  • Recognition and expression of size communicates measurement relationships

  • Measurement takes different forms.

  • Computation and fluency in basic mathematical operations are vital skills.

  • Estimation and computation are vital tools.

  • There are many ways to solve a problem.

  • Multiplication is repeated addition.

  • Addition and subtraction are related.

 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 vocabulary?

  • In what ways can numbers be communicated, represented, and ordered?

  • What are the different ways to communicate solutions to problems?

  • What essential components are needed to solve problems?

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

  • What are the graphic tools we use to clarify data and when do we use them?

  • Why is computation and fluency in basic mathematical operations a vital skill?

  • How is a fraction part of a whole?

  • How can we measure length, liquids, and weight?

  • How can you show the difference between addition and subtraction?

  • How does an array show repeated addition?
     

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!
 Reading and Math Strategies for Parents - includes the top 10 strategies in each subject.
