Website with lesson on tenths and hundredths using grids, fractions, and number lines. (Note: I don’t like the “tagging/adding” zeros part.) []

An idea for a small group or center activity: Teacher should have a baggie or container with 10 two-colored counters and one with 100 two-colored counters. The student will be direct to dump out each of the bags 2 or 3 times separately and record the part of the counters that are red as a fraction, decimal, and a shaded representation on grids. The teacher should provide a handout with hundred’s grids and ten’s grids and places to record the written word, fraction word, and decimal word of the part represented by the tossed counters. Another fun twist to this is to provide sheets of bubble wrap and have them represent a decimal in tenths and a decimal in hundredths with the bubble wrap as an extension.

In this series of 3 hands-on activities, students develop and reinforce their understanding of hundredths as fractions, decimals, and percentages. (Just skip the percentages part.) Students explore using candy pieces as they physically make and connect a set/linear model to area models. []

Website for teacher or parents demonstrating how to teach relating fractions and decimals. The website includes practice word problems and answer keys. []

Website shares a lesson that has students playing a game where they relate fractions to decimals in tenths. []
