decimal secret code cards (place value cards)
expanded form
Unit Overview:
Students will build on their decimal work from fourth grade. Expanded form deepens students’
understanding of place value. They will use expanded form and include fractions (14.3 = 10 + 4 + 3/10).
Students build on their understanding of place value to read, write, and compare decimals to thousandths.
They read decimals using fractional language and write decimals in fractional form. Students need to
understand the size of decimal numbers and relate them to common benchmarks such as 0, 0.5, and 1.
Comparing tenths to tenths, hundredths to hundredths, and thousandths to thousandths is made easier if
students use their understanding of fractions to compare decimals.
Strategies/Skills:
Students are expected to use a variety of methods and strategies to extend their understanding of
decimals.
Number lines
Base ten blocks
Place value charts
