\"Envision
\nAnswer:
\n\"\"<\/p>\n

Explanation:
\nI kept 2 counters in the red five-frame. Used a red crayon and wrote the number 2 that tells how many counters are in the red frame. I kept the same number of counters in the blue five-frame. Used a blue crayon and write the number that tells how many counters are in the blue frames.
\nThe red nmber is smaller by ten then the blue number,
\nThe pattern is 2,12.<\/p>\n

Directions<\/strong> Say: Put some counters in the red five-frame. Use a red crayon and write the number that tells how many counters are in the red frame. Put the same number of counters in the blue five-frame. Use a blue crayon and write the number that tells how many counters are in the blue frames. Show the numbers to a partner. Compare your answers and look for patterns. How is your blue number like your red number? How is it different?<\/p>\n
