Today We Will … • Today we will identify percents and values that are equal to ¼, ½, ¾, and 4/4. • Grade Level Expectation: Use common equivalent reference points for percents ( ¼, ½, ¾, and 1 whole)
STEP OUT – Strand & Assessment Guide N-2-E: Demonstrate number sense and estimation skills, giving particular attention to common equivalent reference points (for example, ¼ = 25% ; ½ = 50% ; $1 = 100%) Assessment Guide: Use common reference points, including relating fractions for half and fourths to their percent equivalents (for example, identify a value as “between ¼ and ½” or “about 50%”; or recognize that ¼ = 25%, or ¾ is between 50% and 100%) .
Is 1 whole the same as 4/4 ? 4/4 4 out of 4 1 whole pizza 1 whole is the same as 4/4
If you ate 1 out of the two pieces of the pizza below what fraction of the pizza would you have eaten? Divide the whole into two equal pieces ½ one out of two
How many slices represent ¼ of the pizza? One slice represents 1/4 Divide the whole into four equal pieces One out of 4 equal pieces = 1/4
How many slices represent ¾ of the pizza? Divide the whole into four equal pieces Three slices represents 3/4 Three out of 4 equal pieces = 3/4
What does the denominator tell us? The denominator tells us how many parts we will divide something into. This denominator tells me I will divide the whole into 2 equal parts.
How many sections would you have if I gave you ½ of my whole graham cracker? I whole = 4/4 4 out of 4 You would have two sections of the graham cracker. Divide the whole into two equal pieces
How many sections would you have if I gave you 1/4 of my whole graham cracker? One out of 4 = 1/4 Divide the whole into four equal pieces You would have one section.
Amy ate ¾ of the graham cracker. How many sections did she eat? Three out of 4 = 3/4 Divide the whole into four equal pieces Amy ate three sections.
How many quarters are in a dollar? How does this relate to fractions?
Let’s find equilivant percents for ¼, ½, ¾, and 4/4. ¼ 25% ½ 50% ¾ 75% 4/4 100%
Let’s do this one together…. ¼ 25% ½ 50% ¾ 75% 4/4 100%
The good news is the Graham Cracker Mat will help us figure out fractions and percents… 6 9 12 3 Step 4: Add the number in ¼ column with the number in ½ column to get ¾. Step 3: Divide by 2 again 6 ÷ 2 Step 1: Write the whole amount. Step 2: Divide by 2 12 ÷ 2
Mary had 16 beans and gave David 75% of them. How many did she give away? Mary gave away 12 beans. 4 8 12 16 Step 4: Add the number in ¼ column with the number in ½ column to get ¾. Step 3: Divide by 2 again 8 ÷ 2 Step 1: Write the whole amount. Step 2: Divide by 2 16 ÷ 2
Cole bought 20 pieces of candy and ate 5 of them. What percent of his candy did he eat? 20 15 5 10 Cole ate 25% of his candy.
Independent Practice • Complete practice page 202 in your Math book. • Don’t forget to use the Graham Cracker Mat to help you figure out the answers.
Development • Analyze lesson plans, embedding specific areas to connect student learning to the following descriptors: Most learning objectives and state content standards are communicated. There is evidence that most students demonstrate mastery of the objective.
Objective: The learner will identify percents and values that are equal to ¼, ½, ¾, and 4/4 Grade Level Expectation: Use common equivalent reference points for percents ( ¼, ½, ¾, and 1 whole) Materials: • PPT • Dry Erase Boards, Markers • Graham Crackers • Beans • RallyCoach Worksheet (1 for each pair of students) • Textbook (Student) Anticipatory Set (Attention Getter): RallyRobin – Show students pictures and have them brainstorm thoughts, relative to the next area of study. Lesson: • What we will do today? (PPT/Objective/GLE/Agenda) • Intro: What do you know about these Fractions? ¼. ½, ¾, 4/4 (Chart Results) • Pizza Fraction Review (Dry Erase Boards) • Graham Crackers Fractions (Use Graham Crackers & Dry Erase Boards) • Money / Percents (Questioning) • Graham Cracker Mat Model (Bringing it all together)(Use Bean Counters & Dry Erase Boards) • Practice with support (Dry Erase Boards) • RallyCoach (Paired Practice ) • Independent Practice • Closure (Chart Results) Independent Practice: Math Book, Practice At what point did I check for mastery&communicate objectives?
Classroom Application with Support Participants will apply new learning in the classroom with the support of the master/mentor teacher through modeling, team teaching, or observation/feedback.
Evaluate Impact The leadership team will collect evidence, ensuring proficiency in teaching Standards and Objectives.
