For what age are SumBlox best suited?

SumBlox are great for children and adults of all ages but are best suited, academically, for children ages 2-12.

What mathematical concepts can SumBlox teach?

Students can learn a wealth of information through play and hands-on exploration. These topics include:

Number Sense
  • Number recognition
  • One-to-one correspondence
  • Compare numbers
  • Subitizing
  • Counting
  • Cardinality
  • Number sequence
  • Hierarchical Inclusion
  • Understanding our base-ten system
  • Place value
  • Measuring Lengths
  • Reason abstractly and quantitatively
  • Understand Equivalence
  • Directly compare two objects with a measurable attribute in common
  • Algebraic Thinking
  • Describe measurable attributes of objects, such as length or weight
  • Classify objects into given categories

Addition / Subtraction
  • Solve Addition and Subtraction word problems using objects
  • Compose and decompose numbers
  • Find missing addends
  • Skip counting

Multiplication / Division
  • Define multiplication; emphasis on multiples
  • Find factors of whole numbers and use commutative property of multiplication
  • Classify whole numbers (greater than one) as prime or composite
  • Draw conclusions about the factors of a whole number
  • Use associative property of multiplication
  • Use distributive property of multiplication

Fractions / Adding Fractions
  • Define denominator of fractions
  • Define numerator of fractions within halves, fourths, and eights
  • Find equivalent fractions within thirds, sixths, ninths, and twelfths
  • Compare two fractions using inequality symbols
  • Compare and order three fractions using compound inequalities
  • Find the value of a fraction of a whole number
  • Find the fraction, or part, a given value is of a whole value
  • Add two fractions with the same denominator to get a sum up to one whole and fully decompose a given fraction
  • Add two fraction addends with the same denominator to get a sum greater than one whole
  • Add multiple fraction addends to find sums greater than one whole and represent sums in improper form and mixed numbers
  • Add two fraction addends with different denominators (only having to scale one of the addends)
  • Add three fraction addends with different denominators (only having to scale two of the addends)
  • Add two fractions addends with different denominators (having to scale all addends to find a common denominator)

Are your lessons standard-aligned?

Yes, the concepts that can be taught with SumBlox can be adapted to any state standard, as they work on increasing a deeper understanding of basic mathematical concepts. We do align our activities with the Common Core State Standards and have included a reference card with the set which allows parents and educators to easily see which activity aligns with which standard. As we release new activities and lessons on our webpage, they will be aligned to the Common Core State Standards, listing which standards are addressed in each activity.
