With 2-Digit x 1-Digit Color by Number, the more problems students get right, the more of the picture appears. Students solve each problem, match the answer to the color key, and a hidden picture appears region by region. Students apply partial products or the standard algorithm to two-by-one-digit products. Built for Grade 4 and aligned to 4.NBT.B.5. Print it for morning work and centers or assign the self-checking interactive version for home — each download includes the PDF and the digital answer-key version.
Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
