Information Related to the Attached Activity— QTaxon(s): QT-N-165 Quantile measure: 330Q ®
The Quantile Framework® for Mathematics, developed by educational measurement organization MetaMetrics®, comprises more than 500 QTaxons (skills and concepts) taught from kindergarten through high school. The Quantile Framework depicts the developmental nature of mathematics and the connections between mathematics content across the strands. By matching a student’s Quantile measure (for example, 650Q) to the Quantile measure of a mathematical skill or concept, you can see if the student is ready to learn that skill, needs to learn supporting concepts first, or has already mastered it.

Set A5 H Independent Worksheet 4 Independent Worksheet
Using the Standard Algorithm for 2-Digit by 1-Digit Multiplication Maddie and her mom got 6 boxes of treats for their dogs. There are 34 treats in each box. How many treats did they get for their dogs? To solve this problem, multiply 6 × 34. Here are two different methods: • You can make a sketch and list the partial products. Then you can add them. 34
6
30
180

24
x 6 _____ 6 x 30 = 180 6 x 4 = _____ + 24 204 treats
• You can also multiply by using the standard algorithm. If you use this method, you don’t have to list the partial products. 2
34 x 6 204
Multiply the ones. 6 x 4 = 24 ones. Since 24 is 2 tens plus 4 ones, write the 4 in the ones place and write the 2 tens above the 3 in the tens place. Multiply the tens. 6 x 3 = 18 tens. Add the 2 tens you carried over to the 18 tens. Write 20 tens in the tens and hundreds place.
