# Standards-Based Second Grade: Unit 2

## Addition and Subtraction Within 100

TM2038W

He’s bright and talented and will know as soon as you show him. So will the other students in your class. Whether it’s place value to 100, counting, reading and writing to 1,000; understanding multiplication, adding and subtracting within 100, greater than/less than, missing numbers, strategies, properties, or how many more/less through 1,000, they’ll all latch on to each topic, developing a thirst for new knowledge. That’s because you’ll have the optimal materials to begin exploration of these new math concepts. The intuitive and reproducible nature of this, and all TouchMath programs, will save you time and money. Use these tools to show students, engage students, enhance comprehension, and substantiate their skills.

### Unit 2 Details:

• A brand-new day-by-day C-R-A directed Teacher's Manual makes step-by-step multi-sensory teaching easy.
• Pre- and Posttests for each module measure successes.
• 150 teacher/student approved activity masters engage all learners.
• Six complete modules divided by easy topics.

### Module Details:

• Module 1: Understanding Place Value: 100s, 10s, and 1s
• This module uses various models and approaches to extend the foundation of place value to include three-digit numbers. The strategies begin with representing numbers using base 10 blocks and then incorporating the blocks with pictures and place value charts. The numbers are gradually scaffolded working with increments of 200, eventually developing number value to include expanded notation and compact/standard numerals. Activities using place value charts conclude the instruction as comparisons, unknowns, puzzles, mystery numbers, and riddles are woven throughout the activities. The “Problem Solving” section uses specific approaches to making comparisons, finding unknowns, and solving word problems. The number words for ones, tens, and hundreds are used so that students read the words as they say them.
• Module 2: Counting and Reading to 1,000
• This module focuses on counting to a four-digit number –– scaffolded through practice within each of the hundreds. Associating the written numeral with its verbal name and reinforcing the sequencing of numbers are presented as odd and even numbers, multiples of five, and numbers out of order are included. Puzzles, mazes, dot-to-dots, hidden pictures, and mystery numbers provide a variety of motivating experiences. Sequencing from any number is also presented, scaffolded to include numbers after, then numbers between, and finally numbers before given numbers. The “Problem Solving” section continues to be a focus with comparing numbers, finding unknowns, and solving word problems. Application of place value form is again presented to reinforce understanding of the relationship between counting/reading and place value.
• Module 3: Reading and Writing to 1,000
• The activities in this module contribute to building the skill development of reading numbers, which was initiated in the previous module. Writing numbers up to 1,00 as numerals and words is incorporated, and place value is reinforced. The structure of the module originates with filling in missing numbers on a hundred chart that has the even numbers presented. Reading number words and sequencing them by fives, tens, and hundreds is also included. Student interest is enhanced through dot-to dots with number words, flow charts, and questions about numbers 5, 10, and 100. Matching, mazes, multiple choice questions, and in/out tables are designed to provide practice within each hundred sequence to ensure mastery of reading and writing number names and numerals.
• Module 4: Addition Within 100
• The activities in this module spiral back to Unit 1, Module 4, which uses base 10 blocks and pictures to show regrouping. The learning is extended from adding within 50 to adding within 100. Base 10 blocks and Ten Frames are continued, and visual cues (modified place value charts, arrows, and boxes above the tens to remind students to regroup) replace these models in the next level of scaffolding. The use of TouchPoints is also eliminated. One- or two-step word problems and comparisons are included throughout the section on regrouping with students then progressing to mixed practice. Students apply the concept of regrouping through in/out tables, hundred charts, and tables with the problems and unknowns in all positions.
• Module 5: Subtraction Within 100
• The activities in this module spiral back to Unit 1, Module 5, which uses base 10 blocks and pictures to show regrouping in subtraction. The instruction mirrors that of the previous module in the current unit, Adding within 100. This transference of learning from addition to subtraction further develops the relationship between the two operations.
• Module 6: Mixed Within 100
• The activity pages in this module serve as a review of addition and subtraction. To ensure mastery, visual cues are slowly faded –– all pages continue to show arrows and TouchPoints, however, dotted lines between tens and ones have been removed. The module begins with addition, scaffolding from 30 to 100. Subtraction follows with the same presentation. Finally, addition and subtraction problems are mixed as students are encouraged to identify and color the operation signs before starting to solve the problems.
