What are we targeting?

In early elementary, students first experience patterns involving shapes. They build their understanding first by identifying a pattern, then completing a pattern, and finally extending a pattern. This algebraic thinking and reasoning continue in later grades by recognizing a counting pattern from a list of numbers and then completing that list of numbers following the same pattern. Finally, this understanding of patterns is extended as students identify an operative rule given a series of inputs and outputs in a function.

The relationships observed in patterns of shapes, lists, and rules build the mathematical reasoning that is necessary as students move into deeper algebraic concepts. The points on a linear function are following a pattern, or a rule, such as “add 5.”

**Shapes Description:**

In Patterns with Shapes, Colors, and Real World Objects, students will build a foundation for their algebraic thinking and reasoning skills by identifying, extending, and completing patterns.

**Lists Description:**

Count by 10's

Up/Down by 1000

In Patterns with Lists, students will begin to develop their algebraic thinking and reasoning skills by using the numbers they see in a list to identify what the counting pattern is and complete the list of numbers following the same pattern.

**Rule Description:**

In Patterns with a Rule, students will continue to develop their algebraic reasoning skills by identifying an operative rule being used to show a series of inputs and outputs in a function table.

## How will students see these lessons?

These lessons have been added to multiple grade levels. Patterns with Shapes, Colors, and Real-World Objects can be found in Kindergarten and 1st grade content. Patterns with Lists spans Kindergarten through 3rd grade. Patterns with Rules is found in 3rd and 4th grade content.

**Common Core Standards Met**

Shapes | Lists | Rules |

K.G.A.2* 1.G.A.1* | K.CC.A.1 K.CC.A.2 1.NBT.A.1 1.OA.C.5 1.NBT.C.5 1.NBT.C.6 2.NBT.A.2 2.NBT.B.8 3.OA.D.9* | 3.OA.D.9* 4.OA.C.5 |

These lessons have been carefully integrated into the full suite of DreamBox lessons. Students who are working in lessons beyond these will not need to complete these lessons. If a student is currently working on content at this grade level, then they will see these lessons on their lesson chooser at the appropriate time.
