INCREMENTAL REHEARSAL

• • • • • • Flash cards ( http://www.aplusmath.com/Flashcards/Flashcard_Creator.html

)or index cards with problems students are expected to know Student is given two seconds to answer problems – correct answers into “known” pile, incorrect answers into “unknown pile”. Nine cards are selected from “known” pile; rest discarded.

A review deck is started by teacher reading and answering one problem from the unknown stack; student repeats problem and answer Teacher chooses one “known” card and uses with “unknown” card having student say problem and answer to both; two card sequence continues until each answer is given within two seconds Additional “known” problems are added to the deck until all nine known problems are used with “unknown problem” Review deck now has nine “known” and one “unknown” problem; when each is answered in two seconds or less, one original “known fact is discarded and another “unknown problem is added following the same procedure as above Jim Wright http://www.interventioncentral.org/htmdocs/interventions/math/math_increm_rehearsal.p

INTERSPERSAL WORKSHEETS

• • • Teacher identifies challenging problems for a student Teacher identifies easy problems for a student Worksheet is prepared alternating two types of problems Worksheet Generator for Numbers at http://www.interventioncentral.org/htmdocs/tools/mathprobe/all mult.php

INDIVIDUALIZED SELF CORRECTION CHECKLIST

• • •

Teacher meets with students to analyze mistakes Together develop way to avoid mistake Students use checklist when working independently Zrebiec Uberti, Mastropieri & Scruggs, 2004

COVER-COPY-COMPARE

• Prepare worksheets with problems with answers on left, unsolved problems on right • Student looks at worked problem • Student covers correct problem, works problem on right and checks Jim Wright, http://www.interventioncentral.org/htmdocs/interventions/g enAcademic/ccc.php

‘ERRORLESS LEARNING’ WORKSHEETS

Timed worksheets with include an answer key at the top of the page Student locates answer to problem they cannot work and write it in Caron, T. A. (2007). Learning multiplication the easy way. The Clearing House, 80, 278-282.

MENTAL NUMBER GAMES

• • • A Minute or Less– start with a number and give students an operation and another number. Without telling them the answer, use that answer and give them another number and operation. Operations are performed in the order given.

PAPER AND PENCIL NUMBER GAMES

• • • Give students a number and have them come up with computational problems that fit that number. Give students a date and see how many problems they can write that uses all the digits in that date.

WWC Quick Review of the Article “Promoting Broad and Stable Improvements in Low-Income Children’s Numerical Knowledge Through Playing Number Board Games" 1

What is this study about?

This study examined whether playing number board games improved numeracy skills of low income preschoolers.

It included 136 preschool children from 10 urban Head Start centers. The children ranged in age from four to five-and-a-half years old.

Seventy-two children were randomly selected to play a number board game with a trained experimenter. The other 64 children played a different version of the game using colors instead of numbers.

Numeracy skills were assessed at the end of a two-week period and again nine weeks later.

What did the study authors report? Children who played the number game had better counting and number identification skills than children who played the color game. Children who played the number game were also better at picking the highest number from a pair of numbers and identifying positions on a number line.

The effects persisted nine weeks after the game sessions ended. Estimated effect sizes at that point ranged from 0.55 to 0.80. These effects did not differ by the age of the preschoolers.
