Accelerating Students in Mathematics Bringing Students to Grade Level in a Standards-Based World Strand Trace

What mathematical ideas are embedded in this standard? Grade 3: Order and compare unit fractions and fractions with like denominators by using models and an understanding of the concept of numerator and denominator. How did we learn these ideas?

Conceptual Thought Patterns for Comparing Patterns With a partner, read through each of the examples. Make up some fractions that provide an example of the description. Table sharing.

Finish these fractions so they are close to but greater than one-half. 9 15 12 21 Finish these fractions so they are close to but less than 1 whole. 11 24 16 30

Reflect: Through these two activities: What would students be understanding about fractions?

Conceptual Thought Patterns for Comparing Fractions More of the same-size parts. Same number of parts but different sizes. More or less than one-half or one whole. Distance from one-half or one whole (residual strategy–What’s missing?)

Comparison of Fractions Consider ways to reason with benchmarks when comparing these fractions. 5/7 or3/7 3/8 or 3/4 5/4 or 8/9 15/16 or 9/10 1 1/3 or 6/3

Ordering Fractions on the Number Line Gr. 3 Everyday Math (1)Make fraction cards using the post it notes. One fraction per card. (2)Allow quiet time to think about placements. (3)Taking turns, each person: Make a number line with benchmark numbers; 0, 1, 2, 3. Places one fraction on the number line, and Explains his/her reasoning using benchmarks and conceptual thought patterns.

Reflect As you placed the fractions on the number line, summarize some new reasoning or strengthened understandings.

Fraction Kit Gr. 4 Everyday Math Fold paper strips Purple: Whole strip Green: Halves, Fourths, Eighths Gold: Thirds, Sixths, Ninths, Twelfths

Fraction Strip Observations With your partner, make a few observations about ways to use your fractions strips. Make up two problems for each observation. Present a problem for the class to solve.

Task: Estimation with Benchmarks Table facilitator reveals one problem at a time. Each individual silently estimates. On the facilitator’s cue: – Thumbs up = greater than benchmark – Thumbs down = less than benchmark – Wavering “waffling” = unsure Justify reasoning.

Reflection What are some of the big ideas about fractions you are learning?

Minnesota Standards Fraction Strand Trace Make connections between the big ideas in the fraction standards and the activities for today.

Day 2 Estimating Fractions Operations with Benchmarks Fraction Strand Trace 2 D Geometry

Tricky Triangles Consider: What will students learn? What are the big ideas? 1.Triangles have three sides, three vertices, and three angles. 2.Triangles can be oriented in many different ways. 3.Angles may have the same size or very different sizes. Side lengths may be the same or different.

What idea is important? What question will you ask? Shapes A, C, H, M. Shapes F and O Shapes P and B Shapes E, G, and K

Power Polygons Clear off the table. Find the polygons that are triangles. Put the rest back in the bucket. Take out 8 triangles from each of the bags. (save the plastic bags).

Power Polygons Use your polygons to find pairs of triangles that have an attribute in common. Draw two more triangles that share the attribute and one that does not. Include the following words in your discussion: Acute, obtuse, scalene, isosceles, equilateral Before you start, write a definition for these words on a sheet of paper.

Guess My Rule (5 of each polygon) 1) One person thinks of a rule and, without telling anyone the rule, places two of the polygons that fit the rule on a piece of paper. 2) The same person then picks up a polygon that does not fit the rule and places it off the paper. 3) The other players take turns choosing a new polygon that either fits the rule or does not fit the rule. 4) A rule can be guessed after each player has had a turn to place their polygons.

Important Mathematical Ideas Have three/four/ five sides Have sides that are all the same size Have angles that are all the same size Have angles that are different sizes Have no right angles

Strand Trace Make connections back to the standards.

Shape Cards Study the quadrilaterals Discuss the similarities and the differences in the quadrilaterals. List properties. Construct a table chart. All QuadrilateralsSome Quadrilaterals

What mathematical ideas does the teacher listen for? What are the mathematical ideas that children need to develop with these 2 D shapes?
