This task was designed to support students in developing the concept of ten more and ten less, moving from concrete representation to understanding of the unit of ten within ten more and ten less. Students will also understand the value of ten(s) within any number as they mentally add or subtract 10 from a given number 100-900.

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 * Number cards labeled 1-10 (attached as a PDF) Actions * Begin by playing the game as a whole class to demonstrate the rules and for student...

Students who work on this task will benefit in seeing that given a quantity, there is often more than one way to represent it, which is a precursor to understanding the concept of equivalent expressions.
Material Type: Activity/Lab
The purpose of this task is for students to compare two options for a prize where the value of one is given $2 at a time, giving them an opportunity to "work with equal groups of objects to gain foundations for multiplication." This context also provides students with an introduction to the concept of delayed gratification, or resisting an immediate reward and waiting for a later reward, while working with money.
Material Type: Activity/Lab
This word problem requires students to use addition and subtraction and think about money.
Material Type: Activity/Lab
This task is written so that students have opportunities to use different strategies to determine whether a set has an even or odd number of objects.
Material Type: Activity/Lab
The purpose of this task is for students to determine whether a set of objects (up to 20) has an odd or even number of elements. Students will also write an equation to express an even number as a sum of two equal addends and an odd number as a sum of two equal addends and 1.
Material Type: Activity/Lab
This task aims to give students practice counting and recording the given number on quantities up to 20.
Material Type: Activity/Lab
This activity builds on Sort and Count I. It also helps students become familiar with the math vocabulary more/less/same and most/least as they sort, count, and compare small groups of objects.
Material Type: Activity/Lab
In this lesson students will learn about tallying and collecting data.
Material Type: Lesson Plan
In this activity students become familiar with the math vocabulary more/less/same and most/least as they count and compare small groups.

In this scavenger hunt games students are given the task of finding and identifying real-world shapes in their environment.
Material Type: Activity/Lab
In this scavenger hunt game students practice copying shapes.
Material Type: Activity/Lab
In this "word search" style puzzle students practice identifying sequences of shapes.
Material Type: Activity/Lab
In this game activity students practice comparing shapes and naming something that is alike or different about them.

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.
Material Type: Activity/Lab
In this activity students compare objects to see which is longer and heavier than the other.
Material Type: Activity/Lab
In this activity students become familiar with the words, Ňtaller/shorterÓ as they refer to height.
