Grade 2: October Unit
Color, Shapes, and Patterns (@ 20 days)


Overview

Video Introduction. October focuses on learning critical mathematics skills and includes lessons that focus on using math language to explain and describe patterns, geometric shapes, and answers to math problems, and to tell time. Second graders will experience math activities using shapes to identify, describe, draw, and compare geometric shapes, explore and describe color, shape, and size of shapes, and use shapes to create and reproduce designs and patterns, tell time to the quarter hour, explain the answers to math problems, and demonstrate the difference between adding and subtracting.

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

  • In order to communicate mathematical ideas, 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.

  • Mathematics is dependent on place value.

  • 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.

  • We make predictions based on probability.
    Geometry builds our world.

  • Recognition and expression of size communicates measurement relationships.

  • Appropriate tools and units are needed to measure.

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

  • Estimation and computation are vital 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?

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.

 

Standard 1: Number Sense - October

Identifies place value (ones, tens, hundreds)

Identifies odd/even numbers to 50

Knows different names for the same number

Understand greater than, less than, and equal to

 using whole numbers

 using basic addition and subtraction facts

Adds coins to $1.00 – counting coins, coin combinations, equivalencies of coins

Standard 2: Algebra and Patterns - October

Illustrates number sense using pictures

Identifies, describes, creates, and extends patterns

number patterns – filling in the missing numbers in a pattern

Standard 3: Statistics and Probability - October

Standard 4: Geometry - October

Identifies and sorts geometric shapes by various characteristics

Recognizes and identifies basic geometry terminology

Standard 5: Measurement - October

measure with a ruler to check estimation

Standard 6: Computation - October

Adds and subtracts 2-digit numbers (no borrowing or regrouping)

Number stories using real-world situations

use the correct operation (addition or subtraction)

use the appropriate method to solve the problem

Parents

 You can help your second grader as he/she continues to learn more sophisticated mathematics in quarter 2 by calling attention to times to the quarter hour on digital and analog clocks. Telling time is a complex skill, so lots of practice is in order. Help your child compare like items by color, shape, and size. Slices of bread, fruit, blocks, and other items around the house work well for this activity. Tell simple math stories that involve adding or subtracting small numbers. Have your child tell you about their thinking and how they got the answer.
