Decimals Hundredths Grid
Here are some great decimal grid activities by the Virgina Department of Education (see pages 44 – 52). I love decimal grids! Use them to teach adding, subtracting, multiplying and dividing decimals! Grids are great scaffolds for thinking.

Decimal of the day is another routine that gives students an opportunity to revisit concepts throughout the year. In a decimal of the day routine the teacher writes a decimal like .55 and then the students do a series of activities with that decimal as well as answer some questions about it. For example:
1. Write the decimal in word form
2. Write it in fraction form
3. Write 2 decimals that are great than this number (Show them all on the numberline)
4. Write 2 decimals that are less than this number (Show them all on the numberline)
5. Write the decimal in expanded form
6. Add .9 to this decimal
7. Subtract .9 from this decimal
8. Multiply 2 by this decimal; Write a story about this equation
9. Round it to the nearest tenth and hundreth
10. Compare it with symbols to 2 other decimals

Something everybody needs to know how to do! Here are some great resources that I am encouraging everybody (including the primary teachers) to look at. We all have to step up our game. Every elementary teacher needs to know and be comfortable with solving math problems at least through 8th grade math!!!:) Notice the modeling—this is key. The idea that we conceptually illustrate what is happening is of utmost importance. We need to take this idea of conceptually modeling the math…and do it with whatever we are teaching. Watch how well this is done in the following videos!

Read Full Post | Make a Comment ( None so far )Dividing Decimals at a Concrete Level: Great Guided Math Lessons
The new Math Common Core states that 5th grade students will
Perform operations with multi-digit whole numbers and with decimals to hundredths.
5.NBT.7. Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
So, we need too make sure our students understand decimals thoroughly. We need to teach it at a concrete, pictorial and THEN abstract level. This is the first post of a series that deals with decimals. Here are some resources to teach dividing decimals at a concrete level.

Decimals is a tough concept for many of our students. It is so important that we spend some time building conceptual understanding and problem solving as well as the procedural fluency. I think a great way to start is based on the work of Dr. Bennett from the University of New Hampshire (http://www.decimalsquares.com/). Decimal squares is a way for students to visualize what they are talking about and to develop conceptual understanding.
