Count the bananas. Now choose the best answer. \(8 \, + \, 8 \, = \, x\)

\(0 \, tens \, + \, 8 \, ones \, = \, 8\)

\(8 \, tens \, + \, 0 \, ones \, = \, 19\)

\(0 \, tens \, + \, 8 \, ones \, = \, 20\)

\(0 \, tens \, + \, 8 \, ones \, = \, 8\)

\(8 \, tens \, + \, 0 \, ones \, = \, 8\)

Count the bowls. Now choose the best answer. \(6 \, + \, 6 \, = \, x\)

\(0 \, tens \, + \, 6 \, ones \, = \, 6\)

\(0 \, tens \, + \, 6 \, ones \, = \, 12\)

\(0 \, tens \, + \, 6 \, ones \, = \, 6\)

\(6 \, tens \, + \, 0 \, ones \, = \, 6\)

\(6 \, tens \, + \, 0 \, ones \, = \, 17\)

Count the bicycles. Now choose the best answer. \(12 \, + \, 2 \, = \, x\)

\(1 \, ten \, + \, 2 \, ones \, = \, 12\)

\(2 \, tens \, + \, 1 \, one \, = \, 15\)

\(1 \, ten \, + \, 2 \, ones \, = \, 19\)

\(1 \, ten \, + \, 2 \, ones \, = \, 12\)

\(2 \, tens \, + \, 1 \, one \, = \, 12\)

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

Included Skills:

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.
