Astronomy Number 39 Tracing for a Clever Countdown to Forty
Continue the astronomy lesson from sheet 39 with the full $8 Number Tracing 1–100 collection.
Sheet 39 is shown from top border to the teacher-signature line.
The entire Letter page pairs THIRTY-NINE and 39 with guided writing and an ordered strip from 31 to 40.
A telescope log has thirty-nine tick marks after one section of the sky is checked. Max has room for one more mark before reaching forty. A fresh row of dots would count the same observations in a different arrangement. Try Number 39 Tracing after checking the astronomy total. Compare the tall outline with the small dotted 39 shapes. Say thirty-nine from the word panel and finish by finding the colored box on the strip that starts at 31. The page keeps the astronomy count in view when the objects are put away.
Share the 39 check with a partner
Ask a partner to start at 38 and advance to 39 as the recorder makes one mark. Give a second partner the final addition that produces 40.
At the astronomy station, ask for the difference between 30 and 39. A learner can show the 9 extra units with counters. For a zero, point to the empty space while reading 39.
Let a speaker read the finished astronomy sign while a partner traces 39. Swap jobs and ask Which digit reports nine loose observations, and why does it become zero after the next ten is completed? Listen for an explanation of the 39 count before commenting on the written result.
What does the 39 label count?
Three tens and nine loose marks become four tens when one new observation is added. Put the extra slip into the fourth group rather than leaving it by the old nine. Compare the written 39 and 40 as representations of counts one apart.
Ask for two astronomy reports. The groups contain 30, and the loose count is 9. Once the totals are combined, look at 39 and say which position records the 3 full groups.
Try hearing about the 9 loose units first. Keep the tens on the left of 39. The order of the astronomy reports can change without moving either digit.
Locate 39 on the 31–40 strip
Count 9 places from the left to find 39. Check by reading up from 31. A learner can use 31 as the first spoken value instead of restarting at one.
Point to 38 on the left of 39. Find 40 to the right of 39. Match one step from 39 with an addition or removal in the astronomy count. When the astronomy arrangement changes but the count stays 39, leave the pointer in place.
Hide the shaded 39. Ask the reader to name an uncovered neighbor and predict the hidden numeral. Check it against 39, then let the learner choose a nearby box for a partner to guess.

Six things to listen and look for around 39
- Explain the astronomy display
- Group 39 by tens and ones. Point to the 30 part before describing the extras.
- Manage a turn in 39
- Keep one dotted 39 model visible while changing direction. Pause between 3 and 9.
- Tell THIRTY-NINE from a partial clue
- Read THIRTY-NINE aloud with the numeral in view. Check the letters at its right end.
- Place 39 in a run
- Use 39 to infer a neighbor. Show whether the astronomy total rose or fell.
- Recognize 39 in a new layout
- Rearrange the astronomy pieces. Does 39 still belong on the label?
- Review one 39 attempt
- Match the finished 39 against its outline. Save a movement for another visit.
Carry one observation across the ten boundary
Count three packets and nine loose observation slips. Have the recorder add the fortieth and trade the loose ten for a packet. Let a child use 39 to name the earlier log and 40 to name the updated one. An adult can ask why the numeral changes on both sides of the gap when the telescope recorded only one new item. Refer back to the high loop on the 9 as you trace one earlier record. In a second round ask the learner to show which slips belong to the old nine and which one completed the new packet.
Read the large 39 before using a pencil
Set the astronomy sign by the large 39. Point between its smaller digits and the big outlines. Say thirty-nine while moving a finger from the first numeral to the last.
See which digit of 39 the child notices first. If attention goes straight to the 9, try a bookmark at the left of 39. Let a partner explain the astronomy amount before taking a pencil turn.

Number 39 Tracing with a clear hand movement
For 39, keep the rounded area of 9 high and its stem down toward the baseline. Rehearse that transition on a scrap, then choose from five 39 models on a dotted line. Rest the spare hand on the page during the lift between 3 and 9.
Pick one feature to watch in the 39 attempt. Compare the digit heights, or see where the strokes of 39 meet the lower guide. If one 39 turn needs work, practise it at a larger size before shrinking it.
Four lines of 39 allow several short visits. Save the lower 39 rows for the next astronomy session instead of making the first try last through all twenty models.


Let THIRTY-NINE do a reading job
Say thirty-nine while a learner tracks the capitals. On a second reading, find NINE at the end of THIRTY-NINE while reading the full label. Use the big THIRTY-NINE reference to check a faint letter in its dotted row.
Make separate astronomy labels for 39 and THIRTY-NINE. Ask someone to match both to the count. On the two word rows for 39, a new reader can follow a part of THIRTY-NINE today and return to the rest another day.

Try the astronomy count at home
Make three stacks of ten and a loose row of nine. Add one scrap and trade the ten loose scraps for a fourth stack before changing the printed total.
Keep the astronomy materials in view. Slide the 9 extras to a counted area as the learner counts up from 30. A child who wants more evidence can open one of the ten groups before rechecking 39.
Choose one 39 model to follow. Put the new mark by the astronomy count and have another person read it. Invite the learner to explain the 39 label before giving a spelling cue.
Adjust the next attempt at 39
| 39 response | Prompt | Check Thirty-Nine |
|---|---|---|
| Only the 9 extra units get counted. | Put the 30 portion beside them. | Read the whole label 39 from the joint display. |
| The two 39 digits crowd or touch. | Compare the gap in the large 39. | Follow one 39 pair and lift between shapes. |
| The reader skips part of THIRTY-NINE. | Point through THIRTY-NINE at speech pace. | Match THIRTY-NINE with its separate numeral. |
| The 39 box is guessed from shading. | Name an adjacent printed value. | Find 39 again with the color covered. |
Check the astronomy count before correcting the pencil. If the child says 39 correctly, ask which shape needs a slower try.
Choose a small goal for the next 39 visit
The 39 printable suits children around ages 5–8 who are ready to compare two-digit numbers. Younger children who already recognize 39 can point, speak and move counters while someone else handles the pencil. A confident writer may copy the astronomy label once on a blank slip.
Use one goal during a short return visit. If a child can describe 39 as 3 tens and 9 ones, the next aim might be the shape of the right digit. If both shapes are familiar, put a little more attention on THIRTY-NINE or the place where the target sits on the strip.
Ask which 39 mark the writer would like to save. Keep the child in charge of the final selection and name a feature they can see, such as a clearer gap or a closed loop. It makes a later return to the astronomy lesson feel connected to something they already accomplished.
Five short activities after the astronomy lesson
- Save the 39 record. Draw the astronomy groups on a card. Move an extra piece and decide whether 39 still applies.
- Guess the hidden 39 box. Read 39 and its neighbors, then cover 39. Ask a partner for the missing value.
- Make a new astronomy order. Add one piece to 39. Write 40 together and point to the changed digit or digits.
- Split the 39 writing job. Have a child dictate THIRTY-NINE while an adult writes it. Trace 39 for a second label on the astronomy display.
- Check 39 in a different arrangement. Return the astronomy pieces to a row. Ask a visitor to verify 39 without the first layout.
Other ways to prepare for the 39 lesson
For a shorter writing turn than 39, start with the even-number dice activity. To isolate the shape of 9 before the astronomy activity, try the 1–6 dice practice or the pencil-control path worksheet as a different warm-up.
Look through family play at NAEYC for a way to adapt the astronomy role-play. A family can also choose an idea from PBS KIDS for Parents and give the written THIRTY-NINE sign a job in that game.
