All Ages: Family History

Because dyscalculia often runs in families, a family history of dyscalculia can be a red flag for children with math difficulties.

Preschool (ages 3 - kindergarten)

Difficulty Counting

Young children may find it difficult to remember which number comes next when counting upward (for example, counting 1-10). Children may also lose their place easily or skip numbers.

Challenges with Connecting Numbers/Symbols to Amounts

Identifying a number or symbol that goes with an amount (for example, connecting four apples with the number “4”) can be hard for children with dyscalculia.

Children with dyslexia or with delays in visual skills development may also struggle with number/symbol recognition.

Organizing/Comparing Amounts

Children with dyscalculia may struggle to organize objects (for example, smallest to largest) or compare amounts (for example, “which is more? One or two?”)

School-Age (kindergarten and later)

Using Fingers or other Supports to Keep Track of Numbers

School-aged children may use their fingers to count (beyond an age where it’s expected) or other “tricks” to keep track of numbers. These children often have difficulty keeping number information in working memory and can struggle with remembering numbers.

Children with attention issues or ADHD may also struggle to recall numbers.

Problems Doing Simple Calculations/Math Facts

Children with dyscalculia often struggle with simple mental math (for example, 7+4=11) or with memorizing math facts, like multiplication tables. It can also be challenging for children with dyscalculia to recognize the same math problem when it is written differently (for example, 5+3=8 and 8=3+5).

Some children may have difficulty calculating because executive function skills are still developing.

Challenges with Understanding Decimals and Place Values

As children move beyond counting to 100, they may struggle to understand place value and decimals. For example, a child with dyscalculia may struggle to compare 23,000.00 and 2,300.00.

Difficulty with Math-Related Concepts

Concepts like size, speed, time and amount can be challenging for children with dyscalculia. For example, children may struggle to estimate small quantities of an item without counting each piece. Children with dyscalculia may also have trouble estimating speed or time in daily life (for example, how fast a baseball is coming toward them).

Problems Learning and Using Money

Children with dyscalculia may struggle to learn the values of coins and bills, how to count them and how to make change.

Difficulty Converting and Comparing Fractions

Older school-aged children may struggle to visualize fractions. This can make it hard to convert and compare them, especially when more complex math symbols (like < / >) are added in.

Challenges with Solving Word Problems

Children with dyscalculia may struggle to use information from word problems to correctly solve them. This can be especially difficult when students must keep more than one piece of information from the word problem in working memory while solving it.

Children with attention issues or ADHD may also struggle to organize information from word problems.

Anxiety or Refusal to Participate in Math Activities

Children with dyscalculia may feel anxious when asked to complete math activities or refuse to do them entirely. They may also use challenging behaviors to avoid math.

Children with anxiety may also try to avoid math activities.
