Skills Covered

  • Skip count by 2s, 3s, 4s and 5s along a bead chain
  • Skip count by 6s, 7s, 8s, 9s and 10s
  • Write the multiples of a number in order, as arrow tickets
  • Count on from a multiple to name any bead of a chain
  • See that the chain of n is n bars of n beads
  • Find square numbers: the last ticket of the chain of n is n × n

How to Use This Pack

Five pages, one step of the bead chain work at a time. Page 1 is the chains of 2, 3 and 4, with the chain of 2 worked as an example: on every chain the first and last tickets are printed, and students write the missing tickets at the ends of the bars. A letter over a bead asks for that bead's number: count on from the ticket just before it. Pages 2, 3 and 4 do the same with the chains of 5 and 6, 7 and 8, and 9 and 10; the longer chains wrap into rows of bars, and a dashed wire shows where each row goes on. Page 5 folds the chains into their squares: an example shows the chain of 3 becoming the square of 3, then students write the last ticket under the squares of 2 and 4 to 10 and the multiplication that names it.

In the Classroom

Use the pages after the child has worked with the real short chains: lay a chain out straight on the rug, count the beads aloud, and place an arrow ticket at the end of each bar. Then fold the chain bar by bar and lay the bead square on top to see that it matches. The worksheet is the record of that work. Children who are ready can cover the tickets and skip count from memory, then uncover them to check.

At Home

Thread beads or pasta onto pipe cleaners in groups of the same size and join them into a chain. Count along it together, saying only the last number of each group: 4, 8, 12, 16. Then fold the chain into rows to make a square and count the rows.

Tips for Success

  • Each chain is made of bars that all have the same number of beads, so every ticket is that many more than the one before
  • To name a lettered bead, start at the ticket before it and count on bead by bead
  • The chain of n has n bars, so it has n tickets, and the last one is n × n
  • Folding the chain into rows of bars makes a square: n rows of n beads
  • In black and white, tell the chains apart by counting the beads in one bar

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

  • 2.NBT.A.2 Count up to 1,000, and count by fives, tens and hundreds.
  • 3.OA.C.7 Multiply and divide to 100 fluently with strategies, and by year's end instantly recall every product of two single-digit numbers.
  • 3.OA.D.9 Spot patterns in addition tables, times tables and other arithmetic, and explain them with properties, like why multiples of 5 end in 0 or 5.
