Hands-On Math Attribute Blocks provides an interactive learning environment for learning and enhancing mathematical concepts related to set theory, geometry, number theory, and logical thinking. It is a perfect classroom tool for core mathematics instruction and enrichment. While using this app students will use mathematical thinking skills to solve randomly generated problems. Students will find the challenges solvable through interaction. The skills learned are relevant to the elementary mathematics curriculum. Encourage your students to try Hands-On Math Attribute Blocks, and as they do you will see them get better at many basic math skills. Attribute Blocks offers 8 levels of difficulty. Younger learners will benefit from the settings where the challenge is to place blocks and determine the logical rules for which blocks are accepted and which blocks are rejected. For older students teachers may want to use some of the options where the challenge is to find a missing rule for a pattern or Venn diagram. Targeted Mathematical Development in the Following Areas: Set Theory - Sets, subsets, negations, union, intersection and Venn diagrams Geometry - Names and properties of shapes Number Theory - Sequences and patterns Logic and Reasoning - Solving logical problems using the scientific method, deductive reasoning Levels: Level 1: Shapes and Colors - Getting Familiar with Attribute Blocks Level 2: Classifying Shapes - Recognizing Similar Attributes Level 3: Classifying Shapes using Two Attributes - Recognizing Similarities and Differences Level 4: Logicial Patterns - Recognizing Differences to Develop a Pattern Level 5: 2 x 2 - Logical Problem Solving based on Attributes and Differences Level 6: 3 x 3 - Logical Problem Solving based on Attributes and Differences Level 7: Venn Diagram - Logical Relationships (Two Attributes) Level 8: Venn Diagram - Logical Relationships (Three Attributes)
Number Pieces, by MLC
This app helps students grasp place value and computation with multi-digit numbers using interactive visual tools. Users can manipulate number pieces to add, subtract, multiply, and divide, fostering a deeper mathematical understanding.
- Manipulate ones, tens, and hundreds pieces
- Regroup pieces (e.g., 10 ones to 1 ten)
- Measure array dimensions with an edge piece
- Use drawing and text tools for annotations
- Zoom, scroll, and hide/reveal work
- Share work via image save or share code

Number Pieces helps students develop a deeper understanding of place value while building their computation skills with multi-digit numbers. Students use the number pieces to represent multi-digit numbers, regroup, add, subtract, multiply, and divide. FEATURES • Add and manipulate pieces (ones, tens, and hundreds). • Change the starting set of pieces to a basic or an advanced set. • Join pieces in groups of ten or break them apart (e.g., 10 ones into 1 ten and vice versa). • Use the expanding edge piece like a measuring tape to show the dimensions of arrays created with the pieces. • Choose from three different colors to clearly identify groups or pieces. • Move, rotate, and duplicate pieces individually or as a group. • Use the drawing tools to label representations and show understanding. • Add equations, expressions, and descriptions with the math text and writing tools. • Zoom and scroll to work with larger collections of pieces. • Hide and reveal work with resizable covers to create your own problems and model strategies. • Share your work by saving an image or providing a share code to others.
