Decimals and Fraction Connections

Learners connect tenths and hundredths: they rename tenths as hundredths to add them (3/10 + 4/100 = 34/100), write fractions with denominators 10 and 100 as decimals, place decimals on number lines, and compare decimals to hundredths with >, = and <, always for the same whole.

  • 4 lessons
