Product Description
A Smartboard Lesson
 Using units, tenths and hundredths squares, students will first represent two decimal numbers and then use the models to add and subtract the numbers.
 Using the models, students will discover that .3 or 3/10 is equivalent to .30 or 30/100. Students will observe the need to line up the decimal points on both numbers, rename numbers when carrying and borrowing.
 Problems begin with adding and subtracting tenths and hundredths and moves to extend adding and subtracting to working with units, tenths and hundredths.
 CCSS 5.NBT.7

Included in the zipped file is a smartboard file, a full set of directions, and a template for place value.

Also available in my store are two sets of task cards on Addition and Subtraction of Decimal Numbers. Each set has 32 cards in 8 sets of 4 cards.
