A child adds ten to twenty-three by counting ten separate steps and arrives at thirty-two. The idea of addition may be clear, while the tens structure still needs attention. For Rochor families considering Primary 1 Mathematics tuition, this gives the next lesson a specific job.
Choose a weekday when school, food and travel leave your child ready to handle objects and explain a change. Choose a weekend when a rested start improves participation. The better day supports learning without making the rest of the week difficult.
Before selecting a slot, watch how your child represents a two-digit number. Seeing two tens and three ones creates a useful starting point for understanding what another ten changes.

Find out whether the tens are visible to the child
A child can read twenty-three correctly without yet organising it as two tens and three ones. Adding ten becomes easier to understand when that structure is available.
Use bundles of ten sticks and loose sticks, or a simple drawing. Ask your child to show twenty-three and describe the parts before changing the collection.
If the representation is uncertain, begin there. If it is secure but counting ten steps is unreliable, the tutor can connect the addition to one extra bundle.
Another ten changes the tens, not the ones
Represent 23 with 2 tens and 3 ones. Add a bundle of 10. There are now 3 tens and 3 ones, so 23 + 10 = 33.
The three loose ones remain unchanged. The new bundle contributes a whole ten. This explains why the tens digit increases while the ones digit stays the same in this example.
For a fresh check, add ten to 46. Four tens and six ones become five tens and six ones, giving 56. Ask your child to show what was added and what remained unchanged.

Compare the child’s actual learning windows
A weekday may work well if your child can eat, travel and settle comfortably after school. Look at whether the child can explain a small idea at the proposed hour, rather than only whether the diary has a gap.
A weekend may be more suitable if after-school attention is consistently low. Consider the exact time and surrounding activities. A crowded Saturday may offer less breathing room than an ordinary weekday.
For a Rochor household, include the full journey from the real pickup point to the confirmed venue and home again. Meals and collection arrangements belong in the comparison too.

Connect the bundle to the written number
Useful teaching links the added bundle to its place value. A drawing can later replace the sticks, while the number sentence becomes a short record of the same action.
Then vary the starting number. The learner should identify its tens and ones and explain the new ten, rather than remember only that twenty-three became thirty-three.
Ask how each child gets an independent attempt in the 3-pax group. Shared discussion helps initially, while a new number reveals whether the relationship belongs to the learner.

Look for understanding after the objects are put away
A few days later, offer a different addition of ten with objects available if needed. Leave the worked example out of sight and give your child time to choose a representation.
If the child changes both digits, revisit the unchanged ones. If the representation is sound but the numeral is written incorrectly, connect the quantities to the written places.
Keep the day that supports willing participation and short friendly checks. Clearer tens, sensible answers and fewer hints provide useful evidence before speed becomes the main concern.

Make the starting position clear
The Primary 1 Mathematics tuition overview provides the wider level route. Bring current school materials, a recent independent attempt and a note of the first step that needed help. Preserve the original working so the tutor can inspect your child’s own decisions.
The Rochor tutor guide describes enquiries for families considering the Bukit Timah teaching location near Sixth Avenue MRT, not a separate Rochor classroom. Confirm the venue and placement directly. The MOE primary curriculum and syllabus page provides the official curriculum route.
For a parent–student consultation, share your preferred weekdays or weekends, actual travel starting point and child’s usual energy pattern. Confirm the available lesson time, teaching venue and class fit before enrolment. Sign up after the starting position is clear and the weekly arrangement looks sustainable.
