Get your students practicing with strategies that build conceptual understanding of multiplying and dividing decimal numbers! Multiplying and dividing decimal numbers requires a deep conceptual understanding of place value and multiplication and division of whole numbers. Research shows that students need to create context in mathematics by representing it visually before building a symbolic, abstract understanding. This product helps students to create and become familiar with these visual representations, and in turn, truly understand what it means to multiply and divide decimal numbers.
Included with these task cards is your choice of recording sheets. One recording sheet is a standard blank recording sheet. The other is full of models that require students to use specific strategies learned in class.
-: showing groups by coloring in grids, using number lines to represent repeated subtraction, demonstrating place value understanding by converting values to numbers of tenths or hundredths, and using multiplication to help with division.
-: area models to represent partial products, number lines to represent repeated addition, partial products, and other visual representations.
Each task card presents one story problem that is winter themed. Students must make sense of each problem, and then use a visual representation to solve.
1. One recording is titled "Decimal Operations Recording Sheet". With this recording sheet, students will need to determine whether they should multiply or divide, and may use any strategies to solve.
2. Two sets of recording sheets are titled, "Multiplying Decimals Recording Sheet" on one side, and "Dividing Decimals Recording Sheet" on the other (when printed 2-sided). One of recording sheets is blank, and the other has visual representations for students to use (number lines, area models, grids, etc.) to solve each problem.
Task cards are separated by operation for teacher convenience. One page includes a set of 6 multiplying decimals task cards, and the other page includes a set of 6 dividing decimals task cards. If you are reviewing both standards, I would recommend printing both. If you are focused on only one standard, only that particular set is necessary. Just print, laminate (if desired for future use), and use whatever parts of this product are most useful to you and your students!
I enjoy using these task cards during small group rotations. This way, I am also able to differentiate with the recording sheets.
As always I very much appreciate your purchase, and please let me know if you have any questions! Enjoy! :)
