Common mistakes to watch for

These are mistakes children often make in this class, with a simple way to correct each one.

Top means 'big' and bottom means 'small'.: Use a tall tree: the top is high up, the bottom is low down. (Top, Bottom, Near and Far)
Counting faster means more objects.: Count slowly and touch each object once. The last number you say is the total. (Numbers 1 to 9)
Skipping a number when counting (e.g., 13, 14, 16).: Count slowly, touch each object, and say the number aloud. (Numbers up to 20)
Counting the same object twice when groups overlap.: Move objects one by one into a new pile and count each once. (Adding within 10)
Counting the taken-away objects as part of the answer.: After removing, cover the taken-away objects and count only what is left. (Taking Away within 10)
Counting on from the smaller number is just as easy.: Show that starting from the larger number means fewer jumps. (Adding and Taking Away up to 20)
A bundle of 10 sticks is counted as 1, not 10.: Count the sticks inside the bundle: 1, 2, 3 ... 10. The bundle is ten. (Numbers up to 99)
A shape with 4 sides is always a square.: Show a rectangle and a square together; count sides and corners. Emphasize that both have 4 sides, but a square has all sides equal. (Shapes Around Us)

A 10-minute daily routine

Short, regular practice is easier to keep up than a long weekend session. One routine that fits into a busy evening:

Minutes 1–2, warm-up: ask one quick question aloud (see the list below) and let your child explain how they got the answer.
Minutes 3–7, learn: do one short lesson part on MangoMindz: the picture lesson is read aloud, then a quick check.
Minutes 8–9, use real things: repeat the idea with coins, spoons, rotis, a ruler or the clock at home.
Minute 10, reflect: ask “What was tricky today?” and look at one common mistake from this guide together.

Try this at home

Top, Bottom, Near and Far: Look up the tall tree: the highest part, where the leaves and the bird are, is the top.
Numbers 1 to 9: Count the apples in the basket
Numbers up to 20: Count the apples, touching each once, and choose the number
Adding within 10: Count 3 apples, then 2 mangoes; push them into one pile and count all: 1, 2, 3, 4, 5
Taking Away within 10: Show 6 cubes, cross out 2, count the cubes left: 4
Adding and Taking Away up to 20: Number line jumps: 8 + 5 — start at 8, five +1 jumps to 13

Quick questions to ask aloud

Ask one a day. Let your child answer before you open the answer.

Which part of the cup is the bottom? (The part that touches the table / The part where you drink / The handle)

Show answer
Start with 5 apples. Take away 2. Count the rest: 1, 2, 3. So 3 are left.
