Place Value Addition vs 2nd Grade Math

Place Value Addition helps students understand addition using place value discs. A strong understanding of place value in the base ten system is essential for long-term mathematical learning. In addition, place value helps students understand how regrouping works. The app provides a visual, step-by-step way to add two numbers using place value discs. Students can solve randomly generated problems or enter their own problems. Features: * Numbers with 1–3 digits * Randomly generated problems * Custom problems * Visual place value discs * Step-by-step addition practice * Clear visualization of regrouping Part of the iDevBooks Place Value series: * Place Value Addition * Place Value Subtraction * Place Value Multiplication * Place Value Division Video: Please visit idevbooks.com to see a video of the app. Other iDevBooks Math Apps: Other iDevBooks math apps include Visual Fractions Decimals Percentages, Decimal Rounding, Whole Number Rounding, Column Subtraction, Column Addition, Long Division, Long Multiplication, Lattice Multiplication, Partial Differences Subtraction, Partial Quotients Division, Partial Sums Addition, and more.

Math Galaxy’s Second Grade Math covers all Common Core math standards for second grade as listed below. The concepts are presented in bite-size pieces with an unlimited supply of practice problems and numbers chosen randomly. Illustrations are used throughout to reinforce the concepts. There are review sections and you can be guided through problems step-by-step or just give the final answer. "The French mathematician Jacques S. Hadamard found, in a study of 100 leading mathematicians, that the majority of them were primarily visual in their approach. Some [including Einstein] went further back to sensations of a kinesthetic kind." Scientific American, Sept., 1984, p. 56. The secret to learning math is consistency. Ten minutes or ten problems a day, if done consistently, can yield significant results.
