## Description

- Overview:
- Once students have developed conceptual understanding of the basic operations they need to develop fluency with the facts. One quick way to include daily practice and motivate students to master these basic facts is through the use of the Who Has? card decks. These decks can be created for virtually any topic and frequent use as both a whole class practice or as a center activity for partners or small groups will provide facts practice in a highly-motivating format.

## Standards

# Common Core State Standards Math

Grade 1,Operations and Algebraic ThinkingCluster: Add and subtract within 21

Standard: 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).

Degree of Alignment: 2.3 Strong (4 users)

# Common Core State Standards Math

Grade 3,Operations and Algebraic ThinkingCluster: Multiply and divide within 100

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

Standard: Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:

Degree of Alignment: 1 Limited (4 users)

Cluster: Draw and identify lines and angles, and classify shapes by properties of their lines and angles

Standard: Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

Degree of Alignment: 1 Limited (4 users)

Cluster: Draw and identify lines and angles, and classify shapes by properties of their lines and angles

Standard: Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.

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

Standard: An angle that turns through n one-degree angles is said to have an angle measure of n degrees.

Degree of Alignment: Not Rated (0 users)

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

Standard: 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,” 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.
