Expectations & Examples of Numbers from the 2008 Math Standards Revision (draft) - Grade 2

Count by tens or hundreds forward and backward starting at any number from 1 through 1,000.

  • Count forward by tens starting from 32.

Represent numbers to at least 1,000 in different ways using written words, numerals, or models, and translate among representations. Models may include money, drawings, or manipulatives such as base ten blocks.

Identify relationships between digits and their place values in numbers up to 1,000.

  • In the number 647, there are 6 hundreds, 4 tens, and 7 ones.
  • There are 20 tens in 200 and 10 hundreds in 1,000.
  • There are 23 tens in 230.

Connect the place of a digit with its value in a number and determine the value represented by a digit based on its position in a number.

  • 4 is located in what place in the number 834?
  • What digit is in the hundreds place in 245?

Explain and use strategies for remembering addition and subtraction facts to 20.  For example, since doubles are reliable memory points for most students, one strategy for remembering 7 + 8 = 15 is that it is one more than 7 + 7.

An explanation of why a procedure works would be based on place value and properties of operations.

Add and subtract two-digit numbers mentally and explain the strategies used.

Extend and create additive patterns, including growing patterns, and explain the rule used to extend/create the pattern.

  • 2 + 3 = 5; 20 + 30 = 50; 200 + 300 = 500
