Clothesline Math Presentation

Agenda

◆ Welcome & Norms◆ Why we use a clothesline◆ Clothesline math setup & supplies◆ Sample clothesline math problems◆ Clothesline math links & extensions◆ Creating your own clothesline cards

Norms

◆ Welcome!◆ Start & end on time◆ Be present and interact◆ Take care of needs ◆ Maintain an open mind◆ Any others?

“How am I supposed to teach students grade level content

when their number sense is so weak?

“How can students explore grade-level content and

strengthen their number sense at the same time?

“Number sense encompasses a wide range of abilities, including being able to make reasonable estimates, think and reason flexibly, make sound numerical judgments, and see numbers as useful. Students with number sense have good numerical intuition. When applying computation skills to solve problems, they can judge if solutions are reasonable. Should they forget a procedure or part of a procedure, students with number sense can reason their way to a solution. They see numbers as tools, not barriers. They are curious about numbers and are comfortable with them.” - Marilyn Burns

Why clotheslines?

◆ Easy and inexpensive to use◆ Assists with measurement◆ Spatial relationships (“Space & Place”)◆ Problem solving ◆ Multitude of ways to use cards: whole

numbers, integers, fractions, decimals, percents, & more

Clothesline Setup

Clothesline Cards

◆ Cardstock - landscape ◆ Fold in thirds, then cut◆ Fold in half

◆ Use the same color for each type: Whole numbers, integers, fractions, decimals, percents, variables, etc.

◆ Ways to show equality: Use clothespins/same vertical location on two number lines

◆ Use labels in addition to numbers

Call to Action

Commit to one of these choices:

◆ SET UP a clothesline in your classroom in 2017-18◆ PICK a topic you do not conceptually understand yet and

challenge yourself to solve it using a clothesline◆ IMPLEMENT a clothesline activity with your students and

tweet it out using #TeamTomball & #ClotheslineMath
