The child confuses left and right — and it gets in the way of math

Type: practognostic
What the research says
Spatial concepts are considered the most important condition for forming the structure of number. The quantitative value of a digit is mediated by place-value notation — by the digit's position in the number.
Lalaeva R.I. Dyscalculia in Children, p. 7 (2005)
Intervention work on developing spatial functions includes: orientation in the surrounding space — telling the right side from the left, the directions “up–down”; orientation in one's own body and using it correctly in movement; and developing spatial concepts (spatial gnosis and praxis).

Find its place
Builds: Spatial orientation as the basis of the number sequence
You need: number cards from 1 to 10
  1. Lay the cards out in a row on the table from left to right: 1, 2, 3... 10.
  2. Remove any 3 cards.
  3. Shuffle them. Ask the child to put each one back in its place.
  4. Harder: turn all the cards number side down, leaving one or two as reference points.
  5. Notice which side the child starts from — the left or the right. If they get confused, practice direction separately.

Arrange objects according to a plan
Builds: Transferring spatial relationships from a plan to real space
You need: a sheet of paper as the “room plan,” 4–5 small objects: an eraser, a pencil, a coin, a block
  1. Draw a rectangle and label the sides: “left wall,” “right wall,” “far,” “near.”
  2. Say: “This is a plan of the room seen from above. Put the pencil by the right wall.”
  3. The child puts the pencil in the right place on the plan.
  4. Add a second object: “Put the eraser in the far left corner.”
  5. Harder: the child describes where each object is on their own, using the words “on the left,” “on the right,” “between.”

Trace the maze with your finger
Builds: Keeping the direction of movement on a flat page
You need: a drawn maze (a simple one: 2–3 turns), a pencil
  1. Draw a simple maze: a corridor with 2–3 turns, the start on the left, the finish on the right.
  2. First the child goes through the maze with a finger, without drawing.
  3. Then draws a line with a pencil.
  4. If they make a mistake, they erase it and try again.
  5. Harder: describe the route in words: “first right, then down, then right.”
Lalaeva R.I. Dyscalculia in Children, 2005, p. 100
Finger counting
Builds: Finger gnosis as the basis of the counting system
You need: small objects (toys, blocks) — 5–10 of them, Explain Math to Me number frames
  1. Put 5 toys in front of the child. “Put your left hand next to them. With your right hand, touch each toy in turn — and fold down the fingers of your left hand.”
  2. After counting: “Raise your left hand — show how many you counted.”
  3. Circle all the toys with your hand: “This is how many there are altogether — five.”
  4. Harder: the child puts the objects into an Explain Math to Me frame, touching each one and saying the number.
  5. Repeat with different amounts: from 3 to 10 objects.

Body schema: up — down, forward — back
Builds: Orientation on one's own body — the first stage in developing spatial concepts
You need: a mirror, a colored sticker or a bracelet to mark the right hand
  1. Stand in front of a mirror together. “Raise your right hand. Now your left.” If needed, put a sticker on the right one.
  2. “Show me: where is up? Where is down? Where is the front? Where is the back?” The child shows on their own body.
  3. The “Do what I do” game: the adult makes a movement and the child copies it.
  4. Moving on to objects: “Put the block in front of you. Behind you. To the right. To the left.”
  5. Without orientation on one's own body, orientation on a page and writing problems down correctly are impossible.

Geometric picture
Builds: Orientation on a flat surface, spatial vocabulary
You need: 4 large and 4 small cardboard squares, 3 large and 3 small circles, 1 large and 1 small rectangle, a sheet of A4 paper
  1. Lay all the shapes out on the table. Name them together: squares, circles, rectangles.
  2. Task: “You're an artist. Make a picture out of all the shapes.”
  3. While the child is laying them out, ask: “Where are you putting this circle?”
  4. Afterwards, ask them to come up with a title for the picture.
  5. Ask: “What's in the center? What's around the edges? What's higher — the circles or the squares?”
  6. Watch whether the child uses the words above, below, next to, between, on the left, on the right. If not, prompt them.
  7. Harder: the adult describes a picture in words, and the child lays it out from the description without seeing a model.

Without help
  • Mixes up place values in numbers: writes 42 instead of 24
  • Can't find their way along the number line — doesn't understand that “to the right means bigger”
  • Difficulty writing problems in columns: digits end up in the wrong place-value columns
