Grade 2: May Unit
Symmetry, Shapes, and Measures (@ 15 days)
 

Overview
In May of second grade mathematics, students will review the following critical skills in mathematics; communication, computation in the four basic operations (addition, subtraction, multiplication, and division), place value, odd and even numbers, data/predictions/probability, coordinate planes, perimeter and area, and a variety of problem solving strategies. Second graders will prepare for third grade mathematics by solidifying their understanding of the following concepts; recognizing symmetry, knowing the characteristics of 2 and 3-dimensional shapes, knowing place value to 100,000, finding patterns in pictures, functions, and in/out boxes, and reading and using a ruler.

Standards

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

  • Mathematics is dependent on place value.

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

  • A sense of number is necessary to solve problems and communicate the reasoning used to predict outcomes.

  • Graphics are tools used to clarify data.

  • Interpreting data displays helps us make sense of information.

  • Geometry builds our world.

  • 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 most important “big picture” questions students should be able to answer after completing learning activities.

  • How does a digit's place in a larger number effect its value?

  • How can math words help us communicate the solutions to problems?

  • How do patterns help us make sense of our world?

  • In what ways do graphic representations help us understand information?

  • How do predictions and estimations help us determine if our answers are reasonable?

  • Why do we need to be fluent at computation?

  • 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 - May

Explain answers to math problems

Demonstrate the difference between adding and subtracting

Review fractions

Standard 3:  Statistics and Probability - May

Describe orally the relationship between a graph and a table

Standard 5:  Measurement - May

Describe the unit for measuring time, length, capacity, weight, and temperature

Estimate and weigh an object

Measure temperature

Know the number of hours in a day, months in a year, inches in a foot, feet in a yard, and cups in a pint

Standard 6:  Computation - May

Place Value to 100,000

Patterns (pictures, functions, and in/out boxes)

Read and use a ruler

Parents

Help your second grader explore how to explain the answers to math problems. Let your child show you the difference between adding and subtracting. Play with odd and even numbers in the 100's.  Ask him/her to make predictions and solve problems using data from daily events to predict outcomes. Use the vocabulary of prediction and probability (fair, unfair, likely, more likely, less likely) in playing games with spinners or dice. Use the map in the phone book to locate your street. Help your child find the perimeter and area of a shape around the house. Allow your child practice adding and subtracting money. The cost of these simple activities is nothing. The gain in fun, relationship, and mathematics is great!
