Comparison and Relationships
Numbers, expressions, measures, and objects can be compared and related to other numbers, expressions, measures, and objects in different ways.

The Base-Ten Numeration System
The base ten numeration system is a scheme for recording numbers using digits 0-9, groups of ten, and place value.

Practices, Processes, and Proficiencies
Mathematics content and practices can be applied to solve problems.
Essential Questions:

  • How can numbers to 100 be compared and ordered?
Students will know...

  • 1 more, 1 less, 10 more, 10 less express a relationship between two numbers.
  • Numbers can be represented on a hundred chart.
  • Place value can be used to compare and order numbers.
  • Ordering 3 or more numbers is similar to comparing 2 numbers because each number must be compared to each of the other numbers.
  • Some problems can be solved be generating a list of outcomes and organizing that list in a systematic way so all outcomes are accounted for.

Vocabulary:

1 more
1 less
10 more
10 less
equal to (=)
less than
greater than
Students will be skilled at...

  • Writing the numbers that are 1 more or 1 less and 10 more or 10 less than a two-digit number.
  • Using a hundred chart to show the relationships of 1 more than, 1 less than, 10 more than, 10 less than a given number.
  • Comparing two-digit numbers using symbols.
  • Ordering numbers from least to greatest, given 3 two-digit numbers.
  • Making an organized list showing possible solutions.
