Lesson 92: Abacus multiplication test for kids
Level 7, Times Market. 12 answers on the beads and 3 in your head. Get 12 right for the Market Basket sticker.
What your child does, card by card
Times Market test. Facts and parts. PlayType opens the lesson: “Test time. No hints. Show what you know.”
12 test tasks follow, one try each and no hints: work out 3 × 4, 6 × 7, 8 × 9, 5 × 6, 23 × 4, 47 × 6 and 23 × 14. “Task 1 of 12” and so on keeps count.
In your head: the abacus is covered and your child works out 6 × 7, 4 × 8 and 30 × 4, picking each answer from 32, 42, 120 and 140.
You passed! Times Market is done. Next: Sharing Garden!
What this lesson trains
About five minutes and 15 answers. Altogether the child makes 25 bead moves (5 with the top bead, 20 with bottom beads). The largest is 322: hundreds, tens and ones. Then 3 quick looks in your head. 2 of the 12 sums need a friend (“+4 = +5 −1” and “+3 = −7 +10”); the others use free beads.
The sum sheet
The lower window shows the column as a child would write it on paper: one number under another, the current line in yellow, ticks on the lines done. The abacus carries the running total from line to line.
What PlayBuddy and PlayType say
PlayType: “Test time. No hints. Show what you know.”
PlayBuddy: “Click Let's Begin, or press Enter!”
PlayBuddy: “Here comes the last one.”
PlayType: “Now do it in your head.”
The test and its sticker
15 answers, one try each, with no green ring and no help. 12 or more right give the Market Basket sticker; fewer, and PlayBuddy says “Not yet. One more try and you've got this!” and Play again glows. Nothing earned before is taken away.
