More and More Manipulatives!

One of the things we wanted to do with Explain Everything was create some basic classroom manipulatives. Digitally, it's much harder to loose peices to your tangram and pattern block sets than when you're using physical blocks! Below are links to a score of different manipulatives we've put together. Now that scale and position can be locked invidually, students will be able to do a great deal with the various manipulatives.

Pattern Blocks - https://app.box.com/s/ki2t3jy4flwapg6rmmq5
This project contains two slides - one simple set that only has a few peices and then a second with a wider range of peices. Students can lock the relative size of the peices, duplicate them and then go crazy making patters! Possible applications include:
Comparing sizes of angles/side lengths
Measuring the area of various shapes using smaller shapes.

Playing Cards - https://app.box.com/s/mlu05b1ndp7us4jkkkno
While these can't be randomized like regular playing cards, this single slide project contains images of a complete deck. Teachers can use it to create videos to explain an excersize to students or two discuss ways cards can be sorted into groups, (ex; by suit, by colour, by face value) and discuss relationships of probability.

Algebra Tiles - https://app.box.com/s/4k658o7psvwhzr30zz5e
Like traditional algebra tiles, these images can be used to model all sorts of algebra related problems. Containing ones, X tiles and X squared tiles, teachers and students can model addition, subtraction and multiplication tiles.
Ex: Show me how you would solve 2x + 4 = x + 6

Factor/Probability Trees - https://app.box.com/s/4ll8qf3k6ufly8xo8d6z
These branching images can be used to show how numbers grow exponentially larger as they are multiplied further. They can also be used to model probability of multiple independent events.
Ex: Model the following proglem - Bob can choose between three kinds of ice cream and four kinds of toppings for his sundae. How many possible sundaes can he create?

Big Bag of Marbles - https://app.box.com/s/86x2pkprbytdxg9u79hi
While not a perfect representation of randomization (due to the layering affect of Explain Everything's program) this manipulative still provides a fun simulation of real probability. Inside the bag, there are equal numbers of green, red, yellow and blue marbles, but they're all mixed up inside! What are the chances of drawing each colour out of the bag?

To the Count of Ten - Manipulatives, Base Ten, Counting and Multiplication


Below are a selection of slides that provide some cheerful, basic manipulatives for teaching a range of topics. Counting, addition, subtraction, multiplication and place value are among the topics that can be covered using these slides.

Base Ten Blocks - https://app.box.com/s/09z3ikcg44a3u0o5j5pq
The three slides all provide basic manipulatives of base ten blocks, the first zoomed in closer than the later two. The subsequent slides feature place value columns. The first focuses on ones, tens and hundreds while the second can be used to represent decimals, with ones, tenths and hundredths filling the columns.

Lesson/activity ideas:
1) Demonstrating relationships - How many red squares does it take to cover one yellow rod? How many rods are needed to cover one blue block?
2) Representing numbers - How many ways can you show the number 192? (example: 2 squares, 9 rods, 1 block OR 2 squares, 19 rods). Which blocks must you use? Why?
3) Addition and subtraction/performance evaluation - Create a video showing how you would solve 239 + 473.

Multiplication Arrays - https://app.box.com/s/z9lvlego10p831dy9fts
This activity consists of groups of objects that will help students master the basic multiplication facts. The first ten pages focus on just one multiples of just one number each from 1 through 10. The final two pages contain images of all the possible arrays from 1 through 10

Lesson/activity ideas:
1) Counting/representing numbers - Select three rods of five tea pots. How many tea pots in total did you select?
2) Commutative property - What are two ways of showing 4x6?
3) Factoring - 4x6 is 24. What is another multiplication fact that results in the number 24?

Ten Frames and Counting Flowers - https://app.box.com/s/hxkukzjxgfgn4c2nmaen
Thre sets of counting tools are included, the first being a basic ten frame with the dots free moving. The second slide has ten frames representing the numbers 1 through 10 premade. The final slide is effectively like the second, accept instead of ten frames it uses collections of flowers.

Lesson/activity ideas:
1) Counting - Show me the number 6.
2) Multiple representation/ Addition - What are some ways to show the number 15 using different bunches of flowers? Can you show that in an addition sentence?
