Website with lesson on using money to teach decimals ﻿ with money. []

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

Website with lesson on identifying, reading, and writing, tenths and hundredths using models and money. http://russellintascfolio.wikispaces.com/Manipulatives+Lesson+Plan

Website with lesson on comparing and ordering decimals. Also has some connection to money and real world. Only problem is that it continues through thousandths. You’ll have to adjust it to fit. [] Quick review idea- Divide class into two teams. Draw a huge square and divide it into 9 smaller squares under the Elmo or overhead so that it is projected on the board. Place decimal numbers in each square. One member from each team comes to board, gets a fly swatter and faces you, the teacher, as you call out a question. The questions should be read a loud and also placed on the elmo so the visual learners can see them as well. The questions could be as follows: the decimal that has a 4 in the hundredths place, the decimal that is written as 4 and 13 hundredths, the decimal that has a digit in the ones place that is 3 less than the digit in the tenths place, etc. Once the question has been asked students turn around and using their fly swatter hit the correct answer. The first student to hit the correct answer wins a point for that team. You can have the winning player stay up until he loses or have two new ones come up every time. So that students don't have to compete against the same player every time have students switch seating after one full round. This is an awesome game for review. I have used it for multipication, division, subtraction, addition, money and anything else I could think of. My students really really enjoy this game! Be sure, before the game starts, to give consequences for hitting a student with fly swatter. I did and no one ever hit anyone because they didn't want to have to stop playing the game.

The following idea from this math blog, [], states: "The Human Decimal Machine is a way of helping them. On pieces of construction paper, write the digits 0 through 9, and another one with a decimal point, and give one to each learner to represent the card. Tell them the way each one says the decimal point is using the word “and.” Tell them that whoever is to the right of the decimal must be called either “tenths” or “hundredths” or “thousandths,” etc. Have different kids with their cards rearrange themselves and then the other kids read the decimal correctly. For instance, if the persons holding the 9, the decimal and the 5, stand before the class, the kids should read it respectively, as ‘Nine’ ‘and’ ‘five’ ‘tenths’."

This website includes an introductory lesson/activity for place value of decimals with tenths and then has two follow up activities where the kids use concrete representations and calculators to build tenths. []

Website shares a lesson and several games/activities that teach place value of hundredths. These would be good for remediation, small group instruction, and/or centers. []
