🔢 Skip Counting: 2s, 5s, and 10s
Skip counting is one of those foundational skills that looks like simple memorization but is really about pattern recognition. Before your kid can chant "2, 4, 6, 8" from memory, they need to actually SEE why counting by 2s works.
This lesson uses real objects to build the mental model. Your child will physically group items and count by multiples, which creates a concrete foundation they can later draw from when they need to recall the pattern from memory.
What You Need
Grab a pile of small, countable objects. Pennies work well because they're familiar and uniform. Buttons, cereal pieces (Cheerios are great - sturdy and uniform), or small LEGO bricks are also good choices. You want 30-40 items to work with.
The Activity
Step 1: Start with 2s
- Have your child count out 20 objects and lay them all out on the table.
- Ask them to group the objects into pairs. Two in each pile.
- Now count the pairs together: "One pair is 2, two pairs is 4, three pairs is 6."
- Write down the numbers as you go: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20.
- Read the sequence together several times.
Step 2: Move to 5s
- Use the same objects. Have them group into sets of 5.
- This is where fingers come in handy - each hand is 5.
- Count: "5, 10, 15, 20, 25, 30" (you may need to add a few more objects to go higher).
- Write this sequence down next to the first one.
Step 3: Count by 10s
- This is the easiest one because they already know this from counting to 100.
- Group 10 objects together (you can use a small cup or bowl).
- Count: "10, 20, 30, 40, 50" depending on how many objects you have.
Why This Works
Hands-on grouping builds the mental model before memorization. When your child later skip counts from memory, they are picturing those groups in their head. That conceptual understanding is what makes skip counting useful later for multiplication.
Kids who just memorize the pattern without understanding often struggle when they hit multiplication later. This hands-on approach gives them something to reach back to.
Pro Tips
- Use pennies, nickels, and dimes to connect skip counting to money. Two birds, one stone.
- Sing skip counting songs - there are tons on YouTube or Spotify. Silly songs stick best.
- Practice on a number line or hundreds chart by coloring in every 2nd, 5th, or 10th number. Makes the pattern visual.
- Do short sessions - 15-20 minutes max. Do it every other day for the first week, then switch to once or twice a week.
What to Watch For
If your child is counting each object individually instead of the groups, that is normal! It means they are still building the connection. You can help by physically moving the groups as you count: "One group... two... Two groups... four."
Some kids breeze through this. Others need more time with just 2s before moving to 5s. That is fine. Stay with what works for your child.
Parent Script
"Let us count by 2s together. Put your fingers down on each pair as we count." Count slowly: "2, 4, 6, 8, 10, 12, 14, 16, 18, 20." "Can you do the same with these?"
Common Mistakes
- Jumping straight to memorized chanting without the hands-on grouping step. The grouping IS the understanding.
- Using objects that are too small or roll away. Frustrating for little hands.
- Trying all three (2s, 5s, 10s) in one session. Pick one per day.
If Your Child Struggles
Stay with counting by 2s only until it is solid. Use just 10 objects instead of 20. Have them physically move each pair to a new spot as they count it, so the grouping is very concrete.
Challenge Version
Count by 3s and 4s using the same grouping method. Or start from a number other than zero: count by 5s starting at 3 (3, 8, 13, 18, 23...).
Easier Version
Just do counting by 10s. Use their fingers. Each time they put up both hands, that is 10. How high can they count by 10s? Most kids can get to 100.
