# reSolve: Place Value Cards

This sequence of two lessons explores the multiplicative place value properties of numbers. Students learn to represent numbers up to 1000 as multiples of hundreds,tens and ones. Students skip count according to random arrangements of place value cards and explore whether the order of the cards affects the totals. They then use a random place value generator to skip count and apply their place value understanding to rearrange and regroup numbers. Each lesson is outlined in detail including curriculum links, vocabulary, materials needed, sample answers, discussion points and student resources such as slide shows and spreadsheets. This sequence is part of the reSolve: Mathematics by Inquiry program.
