# Complete text alternative · 91–120 chart and line

The [A4 landscape visual](number-chart.svg) has three rows of ten labelled cells and one equally spaced line. It is a navigational and comparison aid, not a replacement for counting verified groups or a held-out independent check.

| Row | Read left to right |
| --- | --- |
| 1 | 91, 92, 93, 94, 95, 96, 97, 98, 99, 100 |
| 2 | 101, 102, 103, 104, 105, 106, 107, 108, 109, 110 |
| 3 | 111, 112, 113, 114, 115, 116, 117, 118, 119, 120 |

Each cell is one more than the cell immediately before it in reading order. The end of each row is **100**, **110**, or **120**. Moving down one row in the same column adds ten. The line begins at **90** and ends at **120**; every neighbouring tick is one whole number apart. The longer, labelled ticks are 90, 100, 110 and 120. The ten short intervals between 100 and 110 contain nine interior whole-number ticks, 101 through 109. A tactile version may use 31 equally spaced raised marks, with a distinct texture at 90, 100, 110 and 120. Read the labels aloud only when the task permits that access support.

The bottom reminder says **10 ones = 1 ten; 10 tens = 1 hundred; 120 = 100 + 20 = 12 tens**. To make 120, count a hundred square *or* its ten replacement strips, plus two further strips. Do not count both the square and those same ten strips. On a HUNDREDS/TENS/ONES mat, 103 is one hundred, zero **separate** tens and three loose ones; this does not mean 103 contains no groups of ten.

**How to use without sight:** an adult can place a marker under the learner's direction on the tactile sequence, announce the starting labelled decade and read each requested step. For a quantity target, offer audited ten-strips and a hundred bundle with distinguishable textures. If an adult chooses a position or completes an exchange for the learner, record that mathematical assistance rather than treating it as independent evidence.
