Count the action figures. Now choose the best answer. \(4 \, + \, 4 \, = \, x\)

\(0 \, tens \, + \, 4 \, ones \, = \, 4\)

\(0 \, tens \, + \, 4 \, ones \, = \, 17\)

\(4 \, tens \, + \, 0 \, ones \, = \, 13\)

\(0 \, tens \, + \, 4 \, ones \, = \, 4\)

\(4 \, tens \, + \, 0 \, ones \, = \, 4\)

Count the ants. Now choose the best answer. \(5 \, + \, 5 \, = \, x\)

\(0 \, tens \, + \, 5 \, ones \, = \, 5\)

\(5 \, tens \, + \, 0 \, ones \, = \, 13\)

\(5 \, tens \, + \, 0 \, ones \, = \, 5\)

\(0 \, tens \, + \, 5 \, ones \, = \, 5\)

\(0 \, tens \, + \, 5 \, ones \, = \, 16\)

Count the sports cars. Now choose the best answer. \(3 \, + \, 3 \, = \, x\)

\(0 \, tens \, + \, 3 \, ones \, = \, 3\)

\(3 \, tens \, + \, 0 \, ones \, = \, 3\)

\(0 \, tens \, + \, 3 \, ones \, = \, 3\)

\(0 \, tens \, + \, 3 \, ones \, = \, 17\)

\(3 \, tens \, + \, 0 \, ones \, = \, 14\)

Grade 1 - Number

Standard 1.N.3 - Count the objects from 1 to 20. Split the number into tens and ones to complete the equation.

Included Skills: Counting

Demonstrate an understanding of counting by: • indicating that the last number said identifies “how many” • showing that any set has only one count • using the counting on strategy • using parts or equal groups to count sets. • Achievement Indicators - Answer the question, “How many are in the set?” using the last number counted in a given set. - Identify and correct counting errors in a given counting sequence. - Show that the count of the number of objects in a given set does not change regardless of the order in which the objects are counted. - Count the number of objects in a given set, rearrange the objects, predict the new count and recount to verify the prediction. - Determine the total number of objects in a given set, starting from a known quantity and counting on. - Count quantity using groups of 2s, 5s or 10s and counting on.
