This task aims to give students practice counting and recording the given number on quantities up to 20.
This task requires students to think about and compare fractions.
This task adds some rigor to the activity of growing bean plants. By collecting growth data, students practice measuring and recording length measurements.
This marbel counting iteration of greater than, less than, and equal to with a specific "target number" help strengthen the concept for students.
This task involves fraction multiplication that can be solved with pictures or number lines.
In this activity students measure their hand span. A line graph is used to record the data from the glass.
In this activity using a balance scale students practice weighing items to see how heavy they are. Cubes are used in the balance as units of measure so students may easily count them.
Students work in pairs to measure length by lining up cubes along the longest side of an item. They count and record length by counting the number of cubes.
This task gives children an opportunity to subtract a three-digit number including a zero that requires regrouping. The solutions show how students can solve this problem before they have learned the traditional algorithm.
This task requires students to add tenths and hundredths.
The purpose of this task is to help students see the connection between aÖb and ab in a particular concrete example. The relationship between the division problem 3Ö8 and the fraction 3/8 is actually very subtle.
This task addresses the division problem 4Ö1/3.
This task provides a context for performing division of a whole number by a unit fraction. This problem is a "How many groups?'' example of division.
Students play a game in pairs to read and recognize numbers using a 100 chart.
A slide deck of mathematical questions that revolve around an image. Contains six grade level aligned questions, standards alignment across related domains to demonstrate a potential progression of questions across grade, and related “After the Image” questions and activities to do at home.
The goal of this task is to work on finding multiples of some whole numbers.
The purpose of this task is to help students articulate their addition strategies and would be most appropriately used once students have a solid understanding of coin values.
The purpose of this task is to present students with a situation where it is natural to add fraction with unlike denominators; it can be used for either assessment or instructional purposes.
The purpose of this task is to present students with a context where they need to explain why two simple fractions are equivalent.
This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. 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: #### Materials * 10-15 quart plastic bags of various counters (different numbers of counters in each bag) * A recording sheet for the activity with pic...
