Frame abacus (wooden) with 100 beads for School Maths Lab

Quick Answer: Frame abacus (wooden) with 100 beads for School Maths Lab is a wooden counting frame holding one hundred sliding beads, normally arranged in ten rows of ten. The wooden frame abacus is used for counting to 100, number bonds to ten, adding by bridging through ten and early multiplication.

One Hundred Beads in Rows of Ten

On a frame abacus of this kind every bead is worth one, whatever row it is on. That makes it different from a place-value abacus, where a bead’s value depends on its rod. The rows simply organise the hundred beads into tens, so children can count in ones, see groups of ten at a glance and count on in tens down the rows. It is a counting and calculating frame rather than a place-value tool.

Number bonds to ten come straight from one row. Push seven beads across and three remain, so 7 + 3 = 10 and 10 − 7 = 3. With that fact secure, children learn to add by bridging through ten: for 8 + 5, they slide eight beads, complete the row with two more, then take three on the next row, reading the answer as ten and three, 13. The abacus shows why the method works.

Rows also make multiplication visible. Three rows of four beads show 3 × 4 as an array, and turning the idea round, four rows of three, shows that the answer is the same. With all hundred beads in view, each bead is also one percent of the whole, so pushing across 35 beads shows 35 out of 100, or 35 percent.

Applications

• Counting to 100 in ones and in tens
• Number bonds to ten using a single row
• Adding and subtracting by bridging through ten
• Showing multiplication facts as arrays of rows
• Introducing percentages as beads out of 100

Specifications

Care & Handling

• Keep the wooden frame abacus dry; damp wood can swell and make the beads stick.
• Slide all beads back to one side before storing so the next lesson starts from zero.
• Lift the frame by its sides, not by the rods.

Why Choose LabEquip

Pre-primary and early primary teachers usually buy a frame for each table, since young children learn number facts most easily by moving the beads themselves. LabEquip lists it in Mathematics School Lab Products; for place-value work the Abacus, Superior is the matching tool. Enquire through the contact page.

Frequently Asked Questions

How is a frame abacus different from a place-value abacus?

On a frame abacus every bead counts as one and the rows group the beads into tens. On a place-value abacus, a bead on the tens rod is worth ten and one on the hundreds rod is worth a hundred, so bead values change with position.

How are number bonds to ten shown on the abacus?

Use one row of ten beads. Slide some across and count the beads left behind; together they always make ten. Moving seven beads leaves three, so 7 + 3 = 10.

How does the abacus teach bridging through ten?

For 8 + 5, slide eight beads, then two more to finish the row, then three on the next row. The answer reads as one full row and three, which is 13. Children see how splitting 5 into 2 and 3 makes the sum easier.

How are multiplication facts shown?

Slide the same number of beads across on several rows. Three rows of four beads show 3 × 4 = 12, and four rows of three show the same total, which demonstrates that the order of multiplication does not matter.

How does the abacus introduce percentages?

With a hundred beads in total, each bead is one percent. Sliding 35 beads across shows 35 out of 100, which is 35 percent.

How should a wooden abacus be looked after?

Keep it dry and out of direct sun, and wipe it with a dry cloth. Damp can swell the wood and make beads stick, and heat can crack the frame.
