Learning Domain: Operations and Algebraic Thinking

Standard: Multiply and divide within 100

Indicator: Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 x 5 = 40, one knows 40 Ö 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of one-digit numbers.

Learning Domain: Operations and Algebraic Thinking

Standard: Add and subtract within 21

Indicator: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

Learning Domain: Measurement and Data

Standard: Geometric measurement: understand concepts of angle and measure angles

Indicator: An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a "one-degree angle,"ť and can be used to measure angles.

What is this? Once students have developed a conceptual understanding, they can use this activity to help them become more with basic addition/subtraction facts.2.OA.2 Fluently add and subtract within 20 using mental strategies. By the end of Grade 2, know from memory all sums of two one digit numbers.

Strength: I like how this activity can be used with any topic.

Limitation: Students do need to have a good conceptual understanding before participating in this activity.

Recommendation: This can be used as a quick "Ten Minute" math type activity.
