Place Value Activities ~ 2nd Grade

 

Second graders are really working on place value concepts.  This first week, we have mostly focused on numbers between 1-100; however, in the next couple weeks we will be doing similar place value explorations with numbers to 1000.  Below students are working with a partner to build the numbers written in the tray.  We also played a cover up bingo game that had models of place value blocks.

 

In addition to being able to use models to represent a number, we are also working on describing and representing numbers in many ways.  For example, telling if a number is odd or even, writing numbers in expanded form, and describing value of the digits by their place.  Riddles have been an excellent way for the students to apply all their number sense and problem solve.  This week for homework the students all wrote a number riddle.  Tomorrow the students will exchange riddles and solve. They have really put a lot of thinking into the riddles.

One of my favorite games is called "Digit, Place." There is so much strategy and reasoning involved. One player picks a 2-digit number and the other player has to guess what it is. Player 1 keeps a chart telling the guesser how many correct digits were in the guess, and how many were in the right place. Player 2 will keep guessing numbers based on the previous responses until he/she gets the right number.  Watch this quick video of the student playing.

Here is a list of interactive web based games.  Each game works on place value concepts. Your child can click on the links for extra at home practice.

We have a great app called Mystery Number that is similar to this the number riddle games we have been playing.  The app contains four different games that give students lots of opportunities to explore concepts of number and place value. The games can be played with one player or two.  Check out Mystery Number ($1.99) on the app store.
