Math Terminology for Module 1

Familiar Terms and Symbols

• Make ten and subtract from ten (e.g., 8 + 3 = 8+ 2 + 1 and 15 – 7 = 10 – 7 + 5 = 3 + 5)
• Ten plus (e.g., 10 + 3 = 13, 30 + 5 = 35, 70 + 8 = 78)
• Number bond (e.g., 5 + 1 = 6, 1 + 5 = 6, 6 – 1 = 5, 6 – 5 = 1)
• Say Ten counting (e.g., 11 is “1 ten 1,” 12 is “1 ten 2,” twenty is “2 tens,” 27 is “2 tens 7,” 35 is “3 tens 5,” 100 is “1 hundred,” 146 is “1 hundred 4 tens 6”)
