Both the second graders and third graders are working on place value concepts. While the objective above is a second grade objective, third graders have the same objective but are working with numbers to 10,000 (and with this group we just went ahead to the millions). Here is a peak at some of the games and activities we are using in class to explore place value.
Here are some math magicians working with place value riddles. I read the riddle and the students had to use their wands to find the number that matched the criteria. For instance, one clue said to find a number with all odd digits. Another clue asked the children to find the number that had 80 tens. I had three different sets of cards for challenging all my math magicians. In the next coming weeks we will be working with more riddles with more independence.
We have also been working a lot in our interactive notebooks. Above, the boys are spinning a number to write in standard form. Under the flap, they wrote the same number in expanded form.
Another favorite activity for practicing expanded form was "Number Grab Bag." Inside the bag were 1s, 10s, 100s, 1000s, and 10000s. Students would grab a handful and figure out the number in standard form. Next, they recorded the number in expanded form. We had a great discussion about the importance of zero as a place holder.
We have had lots of different matching activities so students are practicing seeing large numbers in word form, standard form, models, and expanded form. The students are doing fantastic.
In class, the students loved a free app called Math Slides. We have been playing the place value version, as well as, the numbers >1000. Another great way to practice these important place value concepts at home.
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.

Another great app is called Mystery Number. It 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.
