Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: What time was it 2011 minutes after the beginning of January 1, 2011?...
5th grade students work together in teams to create an ecosystem to support Pacific Northwest pollinators.
This lesson plan and assessment takes you on a journey to discover if pollinators find your campus a hospitable home. Core compliant for Grades 3-5, but adaptable to all ages. Are you working with distance learners or in a non-traditional teaching environment? This lesson plan is perfect for you! All you need is a pencil and outdoor space, including sidewalks, local parks, greenways, libraries, and beyond!
This task gives students word problems with a given a set of a specified size and a specified number of subsets. The questions ask the student to find out the size of each of the subsets.
This activity is a teacher-led demonstration of continental drift and includes a math worksheet for students involving the calculation of continental drift over time. Students will understand what continental drift is, why it occurs, and how earthquakes occur because of it.
In this activity, Harry explains key concepts about liquid volume, standard units of measure, and how to convert between them. Also included: the mini-game Fill It Up, a comic video about measuring ingredients and quiz-show questions.
In Module 2, students apply the patterns of the base ten system to mental strategies and the multiplication and division algorithms.
In Module 2 students apply patterns of the base ten system to mental strategies and a sequential study of multiplication via area diagrams and the distributive property leading to fluency with the standard algorithm. Students move from whole numbers to multiplication with decimals, again using place value as a guide to reason and make estimations about products. Multiplication is explored as a method for expressing equivalent measures in both whole number and decimal forms. A similar sequence for division begins concretely with number disks as an introduction to division with multi-digit divisors and leads student to divide multi-digit whole number and decimal dividends by two-digit divisors using a vertical written method. In addition, students evaluate and write expressions, recording their calculations using the associative property and parentheses. Students apply the work of the module to solve multi-step word problems using multi-digit multiplication and division with unknowns representing either the group size or number of groups. An emphasis on the reasonableness of both products and quotients, interpretation of remainders and reasoning about the placement of decimals draws on skills learned throughout the module, including refining knowledge of place value, rounding, and estimation.
Grade 5s Module 4 extends student understanding of fraction operations to multiplication and division of both fractions and decimal fractions. Work proceeds from interpretation of line plots which include fractional measurements to interpreting fractions as division and reasoning about finding fractions of sets through fraction by whole number multiplication. The module proceeds to fraction by fraction multiplication in both fraction and decimal forms. An understanding of multiplication as scaling and multiplication by n/n as multiplication by 1 allows students to reason about products and convert fractions to decimals and vice versa. Students are introduced to the work of division with fractions and decimal fractions. Division cases are limited to division of whole numbers by unit fractions and unit fractions by whole numbers. Decimal fraction divisors are introduced and equivalent fraction and place value thinking allow student to reason about the size of quotients, calculate quotients and sensibly place decimals in quotients. Throughout the module students are asked to reason about these important concepts by interpreting numerical expressions which include fraction and decimal operations and by persevering in solving real-world, multistep problems which include all fraction operations supported by the use of tape diagrams.
Students learn the metric units engineers use to measure mass, distance (or length) and volume. They make estimations using these units and compare their guesses with actual values. To introduce the concepts, the teacher needs access to a meter stick, a one-liter bottle, a glass container that measures milliliters and a gram scale.
Two besotted rulers must embrace proportional units in order to unite their lands. It takes mathematical reasoning to identify the problem, and solution, when engineers from Queentopia and Kingopolis build a bridge to meet in the middle of the river.
The evil Scaleo has escaped from prison and is transforming the length, width, and height of objects until they become useless – or dangerous. Who can put things right? Superheroine Scale Ella uses the power of scale factor to foil the villain.
Students gain an understanding of the layers of the Earth by designing and building clay models.
Students learn about the history of tangrams. They will learn about each piece in the tangram puzzle and analyze the shapes to complete geometric puzzles and mathematics problems.
How far can your vehicle travel? Students design and build a vehicle out of K'Nex with 3-4 wheels, test their designs, analyze their results, make a change, and repeat process. This is a fun STEM activity that can be done with a substitute or if you are getting comfortable with STEM.
