This is a modification of the Illustrative Math lesson, "Ford and Logan add 45 + 36," https://www.illustrativemathematics.org/content-standards/tasks/2068. This lesson was used with a tier 3 fourth grade intervention math group to help students develop their understanding of place value and use of tens language when adding two digit numbers. I modified it to meet the students' needs by adding ways two other students (Sarah and Tammy) solved the problem: Sarah said, "I know 4 tens plus 3 tens is 7 tens; 5 ones plus 6 ones is eleven ones which is 1 ten and 1 one so 4 tens plus 3 tens plus 1 tens is 8 tens and the one left so the answer is 81." Tammy said, " 45 plus 30 is 75, plus 6 more is 81." Students analyzed and discussed all four methods and compared them to their own methods. I then had students practice using the tens and ones language (like Sarah) for some more addition problems without using place value blocks or models.

In this online game, students will be building numbers using Base 10 blocks.  Students decide if they want to select ones, tens, or hundreds.  Students also get to choose if they want to read the number, listen to the number, or if they want to count the blocks given and deterine the number being represented.

In this Flash game, students may use a variety of activities to practice counting, collecting, exchanging, and making change for coins. Coin representations may show their amounts or not; coins may also be represented by coin tiles on a 10x10 grid, to help visualize their values. The five activities are: count, in which students determine the value of a given set of coins; collect, in which students choose coins to represent a given value; exchange, in which students use the smallest number of coins to represent a given value; change from coins, in which students are given a set of coins and asked how much change would be for a dollar (essentially counting up); and change from value, in which students are given a price owed (from a dollar) and asked to make change. There is a "bank" at the lower left side of the applet in which coins may be exchanged for other coins of the same value.

In this task students are required to compare numbers that are identified by word names and not just digits. The order of the numbers described in words are intentionally placed in a different order than their base-ten counterparts so that students need to think carefully about the value of the numbers.

This unit contains two lessons which help students develop number sense through activities involving collection, representation, and analysis of data. Students also practice reading and writing large numbers and develop estimation skills. In Lesson 1, Every Breath You Take, students estimate the number of breaths taken during a specified time, experiment, and display real-life data. In Lesson 2, Making Your First Millions, students develop the concept of a million by working with smaller numerical units, such as blocks of 10 or 100, and then expanding the idea by multiplication or repeated addition. They analyze situations and identify patterns that will enable them to develop the concept of large numbers. Each lesson includes student activity sheets, an instructional plan, and extensions.

This place value and problem solving lesson focuses on forming 3-digit address numbers to meet specific requirement. The lesson provides an opportunity for learners to use the problem-solving strategies of looking for patterns and establishing an organized list. Students also learn that careful reading of information and understanding of mathematical language are important to finding appropriate solutions.

In this task, a group of children sit around a table. Without peeking, they figure out how many feet are under the table. They can use mathematical tools, such as cubes or drawings, that will help them.

I extended off of this to add it to our development of place value, groups of ten, and extra ones. I added an additional material of a tens frame to help students see the grouping of ten and extra ones. After we worked through all the steps (1-6) I added an additional step of scenarios where additional students were added to continue working with larger numbers with groupings of tens and extra ones. As well, students who needed to work with counting on from larger two digit numbers, this activity also helped to increase that knowledge.

Module 4 builds upon Module 2’s work with place value within 20, now focusing on the role of place value in the addition and subtraction of numbers to 40.  Students study, organize, and manipulate numbers within 40.  They compare quantities and begin using the symbols for greater than (>) and less than (<).  Addition and subtraction of tens is another focus of this module as is the use of familiar strategies to add two-digit and single-digit numbers within 40.  Near the end of the module, the focus moves to new ways to represent larger quantities and adding like place value units as students add two-digit numbers.

In this 25-day module of Grade 4, students extend their work with whole numbers.  They begin with large numbers using familiar units (hundreds and thousands) and develop their understanding of millions by building knowledge of the pattern of times ten in the base ten system on the place value chart (4.NBT.1).  They recognize that each sequence of three digits is read as hundreds, tens, and ones followed by the naming of the corresponding base thousand unit (thousand, million, billion).
