The Quantile® Framework for Mathematics, developed by educational measurement and research organization MetaMetrics®, comprises more than 500 skills and concepts (called QTaxons) 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 with the Quantile measure of a mathematical skill or concept, you can determine if the student is ready to learn that skill, needs to learn supporting concepts first, or has already learned it.

Teacher note: In this activity, students will determine addition or subtraction from key words and then add or subtract using different methods. Group size: pairs in whole-group activity Materials: method cards, page 39; key word cards, pages 40-41; number cards, pages 4243; 3 small buckets or boxes Before class: • Make one copy of the method cards and key word cards, and two copies of the number cards. • Cut out all the cards, but keep each set of number cards separate. • Place the key word cards in one bucket, the method cards in another bucket, and one set of the number cards in the third bucket. Directions: • Hand each pair a number card. • Draw 2 number cards out of the bucket. The 2 pairs who have those number cards will go to the front of the room. • One pair will then draw a key word card, and the other pair will draw a method card. • Both pairs will determine the operation (either addition or subtraction) based on the key word and will work the problem with the method chosen. • The rest of the class determines if the problem was completed correctly. Each pair with a correct answer receives a point. If a problem was done incorrectly, discuss it as a class. Ask: Why is it incorrect? Ask: What could be done to make it correct? • After the first problem is completed, students will return the key word and method cards to the correct buckets. • Start again by drawing 2 number cards and repeating this process.
