  2. Text Chapter Seven: Recognizing and Addressing Mathematics Difficulties

  3. Outcomes for Session Three Participants will understand the different categories of math learning disabilities Participants will deepen their understanding of dyscalculia Participants will be able to conduct and interpret math diagnostic screeners to determine the area for intervention

  4. Does the instructional approach impact the determination of a disability? conceptual based math procedural based math reasoning number sense processing speed visual-spatial

  5. Types of Math Disorders Difficulty understanding the concept associated with fluid reasoning Counting Skill Deficits Associated with Number Module dysfunction Arithmetic Skill Number Sense Visual-Spatial Deficit Procedural Disorders Memory Deficit Associated with Executive Functioning Non-verbal reasoning Rapid Recall of over learned material

  10. Quantity Discrimination Number Sense Typically K-1st grade skill; consider using with older students if you suspect a number sense issue; use first grade norms for all grades 2 and above Highly predictive of dyscalculia

  11. Quantity Discrimination • The student is given a sheet containing pairs of numbers. • In each number pair, one number is larger than the other. • The student identifies the larger number in each pair.

  12. Quantity Discrimination

  13. Quantity Discrimination Directions The sheet on your desk has pairs of numbers. In each set, one number is bigger than the other.” “When I say, 'start,' tell me the name of the number that is larger in each pair. Start at the top of this page and work across the page [demonstrate by pointing]. Try to figure out the larger number for each example.. When you come to the end of a row, go to the next row. Are there any questions? [Pause] Start. “ NOTE: If the student has difficulties with speech production, the examiner can use this alternate wording for directions: “When I say, 'start,' point to the number that is larger in each pair”

  18. DPS CBM Benchmark Guidelines for SLD Eligibility Determination The score for fall 1st grade was 8 According to the score where did the student fall for QD for fall 1st grade? • At or Above Benchmark? • Below Benchmark? • Well Below Benchmark?

  19. Missing Number Number Sense Typically K-1st grade skill; consider using with older students if you suspect a number sense issue; use first grade norms for all grades 2 and above Highly predictive of dyscalculia

  20. Missing Number • The student is given a sheet containing multiple number series. • Each series consists of 3-4 numbers that appear in sequential order. • The student states aloud the missing number.

  21. Missing Number

  22. Missing Number Directions “The sheet on your desk has sets of numbers. In each set, a number is missing.” “When I say, 'start,' tell me the name of the number that is missing from each set of numbers. Start at the top of this page and work across the page [demonstrate by pointing]. Try to figure out the missing number for each example.. When you come to the end of a row, go to the next row. Are there any questions? [Pause] Start. “ NOTE: If the student has difficulties with speech production, the examiner can give the student a pencil and use this alternate wording for directions: “When I say, 'start, write in the number that is missing from each set of numbers.”

  28. Math Their Way Screener

  29. Pre-number Concepts K-2nd Grade 2rd-12 grade (select subtest tests based on knowledge of the student’s skills)

  30. Pre-number Concepts and Skills Counting by Rote Memory One-to-One Correspondence Instant Recognition Conservation of Number Counting Backwards Estimation of Objects Numeral Recognition Numeral Forms • How far can you count? • Have the child count as far as possible up to 100. • Have the. child count by 2s, 5s, and 10s. 4 2 … 1 5 3

  31. Pre-number Concepts and Skills Counting by Rote Memory One-to-One Correspondence Conservation of Number Instant Recognition Counting Backwards Estimation of Objects Numeral Recognition Numeral Forms • Objective: verbally counting while physically or mentally touching the object once • Materials: 24 counters, 5 blocks each a different color • Procedure: group counters by 4, 8, and 12; child chooses which to count out loud; count other groups; count all. • 5 blocks of a different color; count the cubes; begin with the blue cube and count all of them; count the cubes but make the green one the last cube; count the cubes but make the yellow cube five

  32. Pre-number Concepts and Skills Counting by Rote Memory One-to-One Correspondence Instant Recognition Conservation of Number Counting Backwards Estimation of Objects Numeral Recognition Numeral Forms • Objective: verbally counting while physically or mentally touching the object once • Materials: 24 counters, 5 blocks each a different color • Procedure: group counters by 4, 8, and 12; child chooses which to count out loud; count other groups; count all. • 5 blocks of a different color; count the cubes; begin with the blue cube and count all of them; count the cubes but make the green one the last cube; count the cubes but make the yellow cube five

  33. Pre-number Concepts and Skills Counting by Rote Memory One-to-One Correspondence Instant Recognition Conservation of Number Counting Backwards Estimation of Objects Numeral Recognition Numeral Forms • Objective: recognized groups of 2,3,4, and 5 w/out counting • Materials: 14 counters • Procedure: group counters 2, 3, 4, and 5 randomly; ask to the child to point to the group of three, four, two, five, three, etc. Do not allow the child time to verbally or physically count the objects

  34. Pre-number Concepts and Skills Counting by Rote Memory One-to-One Correspondence Instant Recognition Conservation of Number Counting Backwards Estimation of Objects Numeral Recognition Numeral Forms • Objective: a quantity remains consistent • Materials: 20 blocks • Procedure: align two sets of 10 blocks; ask to the child if there are the same number of blocks in each set; if the child says “yes” then spread out one set of blocks and then ask if there are the same number of blocks in each set; if the child says “yes” then they have conservation of number; ask the child to explain their answer to make sure it wasn’t a guess

  35. Pre-number Concepts and Skills Counting by Rote Memory One-to-One Correspondence Instant Recognition Conservation of Number Counting Backwards Estimation of Objects Numeral Recognition Numeral Forms • Objective: counting backwards from various starting points • Materials: 20 counters • Procedure: ask child to place 7 counters in a row; cover one counter and ask the child how many are there now; continue covering one counter at a time and asking how many; repeat with larger amounts; add counters and see if the child can count on from the original amount or do they need to count all objects

  36. Pre-number Concepts and Skills Counting by Rote Memory One-to-One Correspondence Instant Recognition Conservation of Number Counting Backwards Estimation of Objects Numeral Recognition Numeral Forms • Objective: counting backwards from various starting points • Materials: 8-10 stacks of Unifix cubes with different number of cubes in each stack • Procedure: place the stacks in a row; point to one stack at a time and ask the child to tell you how many cubes are in each stack; if they count silently ask them to explain to you how they got that number; as you point to the next stack see if they are counting on or backwards or starting from the first cube each time

  37. Pre-number Concepts and Skills Counting by Rote Memory One-to-One Correspondence Instant Recognition Conservation of Number Counting Backwards Estimation of Objects Numeral Recognition Numeral Forms • Objective: estimation of quantity • Materials: 3 jars labeled A, B, C; jar A 25 objects; jar B 50 objects; jar C 100 objects • Procedure: Ask the child toe estimate how many beans are in jar A; then say “If there are ___ beans in jar A, then how many beans do you think there are in Jar B?” ; repeat with Jar C; you are not looking for a accuracy in the estimation but how they compare one jar to another jar; ask the child to explain their estimation

  38. Pre-number Concepts and Skills Counting by Rote Memory One-to-One Correspondence Instant Recognition Conservation of Number Counting Backwards Estimation of Objects Numeral Recognition Numeral Forms • Objective: child names the numeral out of sequence from memory • Materials: number cards 0-10 and 11-20 • Procedure: randomly place number 0-10 on the table; ask the child to point to a number and tell you the name; repeat with numbers 11-20 • Extension: try two and three digit numbers 1 8 3 7 10 0 2 4 9 5 11 18 13 17 20 12 14 19 15
