Entry 9: Shapes...Shapes...and More SHAPES!!! Geometry Revisited

Personal Objective:
Sixth graders have prior knowledge of geometry from previous mathematics courses. When geometry is discussed in their current classroom, they are expected to make a connection between prior and current knowledge. This week's blog will focus on helping students link prior knowledge and newly acquired knowledge.

Common Core Standard:
Sixth Grade: 6.G.A

  1. Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.

Activity:
K-5 Learning:
Other Resources:
Math Antics:
Khan Academy:
Teachers Pay Teachers:
Discussion Question Provided by CK12.org:
If you connect the midpoints on each side of a parallelogram to form a figure, can you find the area of the new quadrilateral? How?
Reflection:
Students will be entering their mathematics classroom with prior knowledge on finding the area of triangles and quadrilaterals. When they look at shapes like parallelograms and trapezoids, they may instantly become overwhelmed. It may be a good idea to suggest that they look at the figure and not immediately try to solve the problem. Doing that may allow the students to see that both parallelograms and trapezoids can be broken down into smaller shapes that they have seen before. Geometry shape manipulatives may be useful with showing students simplified forms.

The worksheets for from K-5 Learning are great tools for reinforcing the main idea of this concept. Math Antics and Khan Academy are two excellent sources for students and are great for visual learners. The exit tickets from Teacher Pay Teachers is a useful way for the teacher to adapt their instructions for students that are struggling with the topic. I have actually seen college instructors use exit tickets in labs. Exit tickets are very helpful for both students and teachers.

    I love the way you set up the questions. I think is a good starter to kind of see where students are at and check prior knowledge. I love videos because is a great way for kids to remember because of the visual concept. Great job! very organized and to the point.

Entry 4: Separating into Groups

Image
Personal Objective: This week I wanted to focus on ways to introduce division to third graders. Common Core Standard: Grade 3: 3OA 2. Interpret whole-number quotients of whole numbers. 3. Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem. 4. Determine the unknown whole number in a multiplication or division equation relating three whole numbers.  Activity: K5 Learning Worksheet Other Resources: Division Mitten From Teachers Pay Teachers McCarthy Math Academy: Division Song Reflection: I found two helpful K5 learning worksheets that addressed the CommonCore standards. While tutoring, I found the division mitten puzzle very useful. My student was struggling with understanding division. The division mitten required the student to be able to understand division in order t

Entry 3: Multiplication or Repeated Addition

Personal Objective: This week I wanted to focus on ways to enhance third graders comprehension of multiplication. The common core standard recommends that a third grade should be to understand that multiplication is the repetition of groups with the same quantity as well as be able to identify the missing number in a multiplication equation. Common Core Standard Third Grade 3.OA 1. Interpret products of whole numbers. 3. Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem. 5. Determine the unknown whole number in a multiplication or division relating three whole numbers. Activity: Other Resources: Multiplication Flower  This technique can be used for numbers 1 through 12.

Entry 6: Fraction Frenzy

Image
Personal Objective: For this week post, I wanted to find supporting materials to aide fourth graders comprehension of fractions and not just skate by. Students can find fractions difficult because fractions contain their own set of rules. Common Core Standard: Fourth Grade: 4.NF Extend understanding of fraction equivalence and ordering. 1. Explain why a fraction a/b is equivalent to a fraction (n x a)/(n x b)  by using visual fraction models, with attention to how the number and size of parts differ even though the to fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. 2. Compare two frications with different numerators,  e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparison with symbols >, =, or <, and justify the conclusions, e.g., by using
