OK, Part 2 of the last post. This list of 9 apps is the folder of math apps I use most often when I visit classrooms that are looking to integrate technology with their math program. These apps can be used as a work station for Guided Math, or tools for the teacher to use when instructing, or for the students themselves. They are also just fun for students to "play" with! These apps, if not free, are very affordable.
1. What's Hiding
This math app is best for students in PreK-Grade 2. Students count the number of shapes that are shown and then the shapes are covered up. Some of the shapes are pulled out from under the cover and students must say how many are still underneath. Great counting, addition and subtraction practice, and wonderful for teaching inverse operation and the "use addition for subtraction" strategy. $0.99.
2. Subitize Tree
I love this app! And kids do too! The old math ninja asks students to get ready for the doors on the tree to open up for a few seconds (3 levels of difficulty). Students have not quite enough time to count how many they see behind the doors before they close again. Then students say how many shapes were shown. If they are correct, they get a point. 4 points sets an animal free from the tree. The picture here shows a ten frame, but there are lots of options to choose from. Lots of fun! $0.99.
3. Hands-On Math Hundreds Chart
This app is a blank Hundreds Chart onto which you can add circles, or black out or highlight numbers. Students can use the app as a tool in much the same way they use a regular 100 Chart, as support for addition, subtraction, patterns, etc. But teachers may use it to have students identify which number comes next in the pattern, which number would be the 10th number, name the pattern rule, and more. Or give students clues to the numbers to highlight, such as "Highlight this number blue: 5 x 9," or "Highlight this number yellow: two tens and one more." The finished product is a picture or word. The picture above is from a nice little blog called Lil Country Kindergarten. If you search for 100 Chart Pictures on Pinterest though, you'll find loads of these 100 Chart pictures, including an awesome sight words product from Jessica Travis! The app is $1.99.
4. Number Pieces Basic
Number Pieces and Number Pieces Basic are two apps that use Base Ten blocks. Basically, anything you can do with Base Ten Blocks, you can do with this app. I really like how the blocks can be joined together, so that 10 units makes 1 ten (a long), and 10 longs can be joined to make 1 hundred (a flat). The blocks can also be broken up into smaller units. The only difference between them is that Number Pieces has a few more features, including a measuring tape that shows the dimensions of arrays that students build. This is an awesome teaching tool! FREE!
This is another app that can be used just like the real item. One of the main differences between this app and the real thing is elastics that don't break, or go flying around the room! :) For younger students, ask them to make the various 2-D shapes. For older students, use for instruction on area and perimeter. Even creating arrays for multiplication facts would be useful. Shapes can be left blank or filled in. Kids love creating their own pictures with this app. The best part? It's FREE!
6. Chicken Coop Fractions
This is a humorous app that students in Grades 4 and up enjoy. There are many different levels of difficulty, so even students in Grade 8 would be challenged by this game. The chickens in the coop each take turns laying eggs. The player must determine where to place the nest so that the egg lands softly. Players must estimate approximately where to place the nest on a number line according to the fraction given. Hilarious! And free.
7. and 8. Kakooma Addition and Kakooma Times
I first heard about these games from Greg Tang at the NCTM conference in Chicago last year (which was an amazing conference, by the way, and I hope to go again this year!). These apps are wonderful for students' practicing their fact fluency. They play against themselves, receiving a score each time, and they try to beat their score with each game. There are four levels of difficulty (Basic, Moderate, Advanced and Expert). The first picture above is a Moderate Addition game. The shape that has a bold border is the series of numbers you look at first. Within the numbers shown, two of those numbers will add to a third number, which is the number to click. In the first picture, 5+2=7, so you click on the seven. Then go to the next series of numbers. The second picture is from the Expert Multiplication game. Way more numbers to choose from! There are Pro versions of these games, but they are more difficult. These games are free to play online from Greg Tang's website, and include an Integers and Fractions version as well. $0.99 each.
9. 5 Dice Order of Operations
I have seen this game played with a deck of cards and a few extra cards with the operations printed on them. You can choose the level of difficulty by clicking on which operations to include. You must use all 5 numbers and whichever operations you need to create the target number shown. The premise is simple, but it's really not that easy! For older students, the order of operations is in effect and must be considered (there is a level which includes brackets). Lots of fun, and quite challenging for older students. Free!
