Sorry for the delay in posting my weekly blog...
This week we are beginning to discover the world of decimal numbers. First, we'll focus on numbers and place value, which will lead into saying and writing numbers with decimals. To reinforce place value, we'll talk about numbers in expanded form:
EX: 145.32 = (1 x 100) + (4 x 10) + (5 x 1) + (3 x 0.1) + (2 x 0.01)
The next topic will be comparing and ordering decimal numbers, and inequalities. We'll continue to focus on place value, and annexing zeroes when necessary to help with the comparision.
Finally, we'll discuss (and review) rounding decimals.
From here, we are going to work on the four basic operations with decimals (addition, subtraction, multiplication & division). I realize that long division is a tricky skill, so when we get to decimal division, we're going to spend some time on long division of whole numbers first. To get ready for this important skill, students must be well versed in the multiplication facts. Please continue to work together on mastery of the basic multiplication facts. We'll be doing the "mad minute" in class each day as practice. Ask your kids about this activity...
