Slice It!

Divide and conquer with clever puzzles that build geometry foundation

  • Kids "slice" each puzzle into a set number of equal parts.

  • Quick Mode presents a fun alternative to regular play.

  • Levels ramp up quickly, but built-in tips and hints can reduce frustration.

  • Kids earn from one to five gold stars depending on how close to equal the pieces are.

Quick Take
Pros: Trial-and-error gameplay supports nimble discovery of concepts and strategies.
Cons: Lacks explicit connection between game principles and classroom learning.
Bottom Line: A fun way for kids to jump into geometry with lessons on shapes, symmetry, and area.
Learning Scores
Engagement Is the product stimulating, entertaining, and engrossing? Will kids want to return?
A fun game to boost lessons on shapes, symmetry, and area. Colorful, hand-drawn illustrations look like doodles on graph paper. Design is cute and should appeal to kids who aren't necessarily math scholars.
Pedagogy Is learning content seamlessly baked-in, and do kids build conceptual understanding? Is the product adaptable and empowering? Will skills transfer? 3
Trial and error puzzling builds geometry knowledge. The addition of explanations using math terms and strategies would help kids connect gameplay to classroom learning.
Support Does the product take into account learners of varying abilities, skill levels, and learning styles? Does it address both struggling and advanced students? 4
Built-in supports help reduce frustration. Two free hints per level give kids a way through tough puzzles. Pop-up tips offer strategies.
Our Review
What's It Like?

Slice It! delivers 200 brain-teasing puzzles that challenge kids' understanding of core geometry concepts including shapes, symmetry, area, and measurement. Each puzzle presents a different shape, which kids must "slice" into a set number of equal parts by using a finger to make a specific number of cuts. Sure, you can cut a circle like a pizza into 12 slices, but what about cutting a trapezoid into 11?

Each puzzle presents the outline of a shape on graph paper along with a target number of slices to make and number of cuts required. Kids draw lines with a finger (or use two fingers to place endpoints for more precision) in order to slice the shape. If they use the correct number of cuts to divide the shape and match the target number of equal pieces, they solve the puzzle and unlock the next one. Puzzles begin as fairly straightforward geometric shapes, but more irregular shapes make solutions less obvious. Kids earn from one to five gold stars depending on how close to equal the pieces are. After each puzzle, kids can view a percentage breakdown for each slice and can retry the puzzle for more accuracy.

Is It Good For Learning?

Kids will like the fun look and feel, with colorful shapes that appear hand-drawn on graph paper. Levels ramp up quickly, but built-in tips and hints can reduce frustration. Kids can replay levels to try and earn the maximum five stars, and they can skip levels they find too difficult. Quick Mode presents a fun alternative to regular play with a set of nearly complete puzzles that have only one slice left to make. Kids will no doubt be engaged, but teachers may need to help them make connections between gameplay, classroom learning, and real-world application.

Though success relies on applying basic geometry knowledge, Slice It! could do better to support a deeper understanding of the math principles behind successful gameplay. Some tips hint at concepts ("Try cutting into four triangles"), but most are simple guidance ("Tap undo to erase the last cut"). In fact, the term area is never used. It would also be great if kids could see a couple alternate solutions before moving on to the next puzzle.

How Can Teachers Use It?

To support a lesson on lines of symmetry or calculating area, you might want to consider Slice It! as an engaging, hands-on way to preview the concepts. Put kids in pairs or small groups to attempt the puzzles and give them a chance to learn through collaborative problem-solving. Since there are multiple ways to solve each puzzle, it would be fun for kids to share out possible solutions as a class. Even before kids learn the specific geometry skills addressed by the puzzles, they may discover fundamental strategies (such as counting grid squares to calculate area) through trial-and-error gameplay.
