Hands-on math: chip trading simulates the use of a popular math manipulative used to teach place value and addition and subtraction with regrouping. chip trading is one of the best ways to help students place value. students place chips representing one, ten, one hundred or one thousand on an interactive playground to represent numbers. chips can be regrouped or exchanged by dragging a virtual manipulative from one column to the next. using hands-on math: chip trading students can develop the following important mathematical concepts: place value concepts regrouping in the ones, tens and hundreds places basic operations: addition and subtraction naming numbers expanded notation reading and writing numbers hands-on math: chip trading is a very useful way for student visualize images of numbers, intuitively understand place value and deepen their understanding of addition and subtraction. use chip trading to have students represent numbers, as well as read and write the numbers. rules for regrouping can be difficult for children. use chip trading to illustrate regrouping by dragging and dropping chips from one column to another. chip trading multi-colored chips are used to represent numbers. four types of chips are used thousands, hundreds, tens and ones. possible topics: place value addition subtraction regrouping naming, reading and writing numbers expanded notation chip trading by tapping an icon a randomly generated problem appears on the screen. using hands-on math chip trading students enter the answer to the problem by moving chips in to columns. if an error occurs, specific feedback about the error is given. progress toward learning objectives is tracked on the scoreboard. -explore place value. -practice addition and subtraction skills. -learn when regrouping is needed. explore and document activities at a variety of skill levels are also provided. students are encouraged to document their discoveries in a journal. here the students are asked to solve a problem that involves regrouping in the ones place. students move chips to solve the problem. the scoreboard keeps track of how many problems are solved at each level. perfect for small group instruction environmentally friendly learning - (no need to photocopy activity pages for each student) a student-centered approach to learning
