This cluster includes the following benchmarks

Code	Description
MA.2.A.4.1:	Extend number patterns to build a foundation for understanding multiples and factors – for example, skip counting by 2's, 5's, 10's.
MA.2.A.4.2:	Classify numbers as odd or even and explain why.
MA.2.A.4.3:	Generalize numeric and non-numeric patterns using words and tables.
MA.2.A.4.4:	Describe and apply equality to solve problems, such as in balancing situations.
MA.2.A.4.5:	Recognize and state rules for functions that use addition and subtraction.

This cluster includes the following access points.

Access Point Number	Access Point Title
MA.2.A.4.In.a:	Identify two-element repeating visual patterns and extend with one repetition.
MA.2.A.4.In.d:	Recognize rules for addition functions, including 1 more and 2 more.
MA.2.A.4.In.b:	Fill in missing items in two-element repeating visual patterns.
MA.2.A.4.In.c:	Identify equal and unequal sets of objects and pictures to 20.

Access Point Number	Access Point Title
MA.2.A.4.Su.a:	Match two-element repeating patterns of sounds, physical movements, and objects.
MA.2.A.4.Su.b:	Use the rule, 1 more, to identify the next number with numbers 1 to 5.
MA.2.A.4.Su.c:	Use one-to-one correspondence to identify sets of objects with the same number to 5.

Access Point Number	Access Point Title
MA.2.A.4.Pa.a:	Recognize a repeated pattern of stimuli, such as sounds or lights.
MA.2.A.4.Pa.b:	Use one-to-one correspondence to identify sets of objects with the same amount to 2.

Vetted resources educators can use to teach the concepts and skills in this topic.

Name	Description
Understanding the Equal Sign:	This lesson helps students to understand the meaning of the equal sign and to realize that one side of an equation must equal (balance) the other side of the equation.
Skip Count by 5s:	Help the Third Little Pig skip count to 1,000 bricks in groups of 5. (Note students are not expected to count from 0-1,000 by 5s, but this activity allows them to experience counting within a variety of contexts between 0 and 1,000.)

Name	Description
Pan Balance - Numbers:	This tool helps students better understand that equality is a relationship and not an operational command to "find the answer." The applet features a pan balance that allows the student to input each half of an equation in the pans, which responds to the numerical expression's value by raising, lowering or balancing.
