21. Use addition and subtraction within 100 to solve word problems involving same units of length, representing the problem with drawings (such as drawings of rulers) and/or equations with a symbol for the unknown number.
Subject: Mathematics (2)
Title: Making a Shelf for Matchbox Cars
Description:

During this explore measurement activity, students will collaborate to solve a real-world math problem. The problem requires students to use multiple addends and report their solution in centimeters.

This activity was created as a result of the ALEX Resource Development Summit.

Title: Matchbox Car Measurement
Description:

This engagement activity allows students to use metric measurements to measure the length of an object. The students will use strategies based on place value and the properties of operation to combine the length of multiple objects with the same length to solve a real-world metric measurement problem.

This activity was created as a result of the ALEX Resource Development Summit.

12. Add and subtract within 1000 using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method.

a. Explain that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.

Title: Solving Real World Measurement Problems
Description:

In this elaborate activity, students will independently solve metric measurement word problems involving length. The students will combine the same length (10 cm.) multiple times. Students will use strategies based on place value and the properties of operation to add within 1,000. The students will use drawings or equations to explain their strategy.
