Product Description
Build your students' ability to compose and decompose two-dimensional figures with this set of 6 fun, easy-to-play games. Your students will ask to play these board and card games again and again, and with each round, they will grow stronger in their ability to compose and decompose two-dimensional figures. With shape cut-out templates for students to physically move around as they play, this set will help your students develop into strong geometric thinkers.

About the Cards

There are three different game types, each with two versions, in this set, for a total of six different games. Four of the games – Build a Shape 1 & 2 and Break it Down 1 & 2– are bingo-type games in that students place colored chips on a grid-like board and try to be the first one to get three or four of their chips in a row. The other game – Compose It! Match Up and Compose It Again! Match Up– is most similar to Memory; in this game, a set of cards are face down and students turn over cards to try to make a match, turning them back down if they are not able to make one.

Game Time!

Build a Shape 1/2

The two versions of Build a Shape are bingo-style games in which students try to place four of their tokens in a row to win. The boards for these games feature grids of composite figures composed of two smaller shapes: squares, right triangles, half-circles, or equilateral triangles, parallelograms, or trapezoids. The students spin each of two spinners and then try to find a figure on the board that can be created by combining those two shapes without overlapping them.

Some of the shapes on the spinners for Build a Shape and Build a Shape 2 are the same, but the figures on the boards are totally different, so each game offers a unique game experience.

Such mental manipulation of shapes is often difficult for students, especially when the shapes share attributes, such as two different types of triangles or a trapezoid and a parallelogram. The provided shape cut-out templates can be extremely useful, especially when the students are playing the games for the first time. The shape cut-outs match the shapes on the spinners, and if students can use these cut-outs to physically combine them in different ways to try to compose one of the figures on the board. If a student spins a square and a half-circle, for instance, they can pick out those two shapes and start to play around with them, physically rotating and flipping them and combining them along different sides.

After some time, your students may not need the cut-outs as they play. You may only have a handful of students that still need the cut-outs. In this case, they can offer a chance to differentiate for varied levels in your class, providing scaffolding for students who still need it.


Break It Down 1/2

The two versions of Build a Shape are bingo-style games in which students try to place four of their tokens in a row to win. The boards for these games feature grids of composite figures composed of two smaller shapes: squares, right triangles, half-circles, or equilateral triangles, parallelograms, or trapezoids. The students spin each of two spinners and then try to find a figure on the board that can be created by combining those two shapes without overlapping them.

The two versions of Break It Down are also bingo-style games in which students try to place four of their tokens in a row to win. The difference between this game and Build a Shape is that in this game, the board features small shapes while the spinners feature composite figures. When playing these games, the students choose one of two spinners to spin. Once the spinner lands on a particular composite figure, the students need to find the two shapes on the board that can be combined to compose the figure spun. Rather than composing a figure from the shapes spun, they are now decomposing the shape spun into two smaller shapes.

As with Build a Shape, the two versions of Break It Down offer unique gameplay experiences. Some of the shapes on the two boards are the same, but the composite figures on the spinners are not the same.

There are shape templates for this pair of games; in this case, the shape templates match the composite figures on the spinners. Rather than combining these figures, the students will have to see how they can be decomposed. These shape templates are best copied, perhaps on cardstock for durability, and then laminated. This would allow students to use dry-erase markers to draw on the template page, drawing lines on the shapes to show how they can be decomposed.


Compose It! & Compose It Again! Match Up

The games Compose It! and Compose It Again! are two variations on the same game, and this game is most similar to Memory. In the games, there are a set of sixteen small shape cards - cards that feature trapezoids, squares, rectangles, parallelograms, triangles, half-circles, and quarter-circles. There are also sets of eight larger composite figure cards - cards that features figures that are composed of two of the shapes featured on the smaller shape cards.

When playing this two-player game, the students take the small cards, shuffle them up, and place them face down in a 4 by 4 grid. The players then shuffle the eight large cards and each player gets four of them. The object is to find the four pairs of shape cards whose shapes can be combined to compose the composite figures on the player's large cards. On each turn, a player picks to small cards and turns them over. If the two shapes can be combined to compose one of the figures on his or her large card, the player takes the two shape cards out of the grid, matches them up with the corresponding figure card, and the turn is over; if the two shapes cannot make one of the player's figures, the shape cards are turned face down and it is the next player's turn.

These two games also come with shape templates that can be used in conjunction with the games. The shape templates feature cut-outs of the shapes featured on the small shape cards. Students can cut out the shapes on these template sheets and use them to physically create the figures on their large composite figure cards.

As with the board games, the two versions of Compose It! Match Up offer unique gameplay experiences. Some of the shapes on the smaller shape cards are identical, but the eight composite figures on the larger cards are different for the two versions.
