Place Value Party
In learning stations, students prepare for a birthday party by using their knowledge of place value to compose, decompose, and represent numbers using standard, word, and expanded forms.
Planting the Seeds of Perimeter
Students will create planters that meet specific perimeter dimensions. The students will need to determine the number of sides and the perimeter for their planter.
Telling Time to the Minute
The lesson requires students to match times to the nearest five-minute interval using an analog clock, digital clock, and time written in words. Students will sing a song, show and write the time to the nearest minute, and tell time using analog watches.
Cooking Up Word Problems
Students rotate through four stations, collaboratively utilizing different strategies and manipulatives to analyze, explore, solve, and generate real-world culinary problem situations.
Are You in Your Place?
Students will be able to use concrete and pictorial models to compose and decompose numbers with place value.
Step Into the Problem: A Strategy for Visualizing a Math Problem
Teachers will show students a tool to help them understand a problem situation. The tool called Step into the Problem, will walk students through the steps of comprehending a problem: Read the problem, Turn and Talk, Act it Out, Notice and Wonder, and Reflect. Students will be given a problem situation and will go through the steps to show that they understand the problem situation.
Shop 'til You Drop
Students will identify the value of coins and determine the total value of a group of coins to select items to purchase from a given list.
Ravaged Robot
Students will learn the concept of area by building a robot using manipulatives and transferring the representation onto grid paper. Then, students will determine the area of each designated body part on their think sheet.
Comparing Fractional Parts
Students will participate in whole-group and small-group instruction as they collaborate and use manipulatives, visuals, and hands-on activities to explore fractional parts. Ultimately, students will understand that when dividing a whole into fractions, the smaller the fractional part, the greater the number of parts, and the larger the part, the fewer the number of parts.
