Module Details:

  • Module 1: Adding 2-Digit Numbers
  • The activities in this module incorporate place value models and charts used in conjunction with pictorial representations. Connecting cubes, beads on strings, and Base 10 blocks are used for hands-on practice making the value of digits inherent throughout the process. The goal is for students to connect the concept of numbers to their quantities. Dotted lines separating tens and ones, and arrows indicating to start with the ones provide additional visual cues with activities carefully scaffolded to assist in building concepts. The activities progress to eliminating the models while maintaining the visual cues and incorporating the use of TouchPoints. Comparisons and word problems are included throughout the module.
  • Module 2: Adding 3 Addends
  • Building on Module 1, adding is extended to three, four, and five addends — gradually scaffolded for sums within 20. TouchPoints are included on all numbers except the greatest addends so that students say the greatest addend and count on the remaining addends. Missing addends are also included to introduce unknowns eventually including sums within 100. The visual cues of dotted lines and arrows continue to assist students when working in columns. Word problems and equations are incorporated as students apply the acquired skills in generating a story or drawing to represent the problem. Regrouping in addition is introduced with models and visual representations of building ten ones to be transferred to the tens column. When students finish this module, they will have had extensive experiences with a variety of addition equations.
  • Module 3: Adding With Strategies
  • The strategies in this module include the commutative property, doubles, build 10 (associative property), easier sums, counting on (using TouchPoints), and multiples of 10. Fact families, multiple experiences with numbers, missing addends, and TouchPoints as visual/kinesthetic cues are all incorporated to provide students with engaging, alternative approaches for mastering sums. When students finish this module, they can consistently apply strategies that are meaningful to them.
  • Module 4: Subtracting 2-Digit Numbers
  • The process used in this module mirrors that of Module 1. The same tactile/kinesthetic models are used: connecting cubes, beads on strings, and Base 10 blocks. The concept of subtraction is further developed using pictorial representations that demonstrate the taking away of objects. Crossing out the number of objects in the subtrahend from the number in the minuend is used to reinforce taking apart or taking away. Throughout the module, TouchPoints are strategically used to aid in the visual/kinesthetic process of subtraction.
  • Module 5: Subtracting With Strategies
  • The strategies in this module include number families, missing numbers, multiples of 10, and counting backward (using TouchPoints). This module mirrors Module 3, reinforcing the relationship between addition and subtraction while showcasing the significance of number families –– identifying the four related facts. The missing numbers activities show students they can use addition to solve subtraction equations. Word problems increase in length and difficulty as students continue to create drawings or stories in real-world situations. Finally, regrouping is pictorially introduced using models and charts designed to be used with concrete models.
  • Module 6: Adding and Subtracting 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.
