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

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

\(8 \, tens \, + \, 0 \, ones \, = \, 13\)

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

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

\(0 \, tens \, + \, 8 \, ones \, = \, 11\)

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

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

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

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

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

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

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

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

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

\(5 \, tens \, + \, 0 \, ones \, = \, 20\)

\(0 \, tens \, + \, 5 \, ones \, = \, 18\)
