Addition | Standard Lesson
Students will create a simple art piece using repeated shapes or images to show addition as putting groups together. They will count and combine parts to make a total, then share their thinking with the class.
| Term | Definition |
|---|---|
| add | To put groups together to find out how many there are in all. |
| total | The whole number after groups are added together. |
| group | A set of objects that belong together. |

Show two small groups of shapes on the board, such as 3 stars and 2 stars. Ask, 'How many in all?' Model counting both groups together.
Look, count, and answer the total aloud.
Give directions for a simple art page: draw or glue two groups of objects, such as 4 red circles and 3 blue circles. Circulate and support counting.
Create two groups of shapes or pictures on their paper and count each group and the total.
Invite a few students to show their artwork and say the addition sentence, such as '4 + 3 = 7.'
Share their art and tell how many are in each group and how many there are in all.
Repeat one or two examples as a class and restate that addition means putting groups together.
Chorally count and answer with the total.
Review that addition is combining groups to find how many are in all. Praise students for using art to show math.
