Make a Ten to Add - Addition Strategy Worksheets

Product description

From the author

Practise making ten to add with 24 printable worksheets. Activities include splitting an addend, completing ten frames, combining three addends and finding a missing number to total ten.

Model the strategy before assigning a page and provide your own answer review. Some printed prompts need correction: the first equation on page 1 omits an addition sign; pages 13–14 include 8 + 1 under a 10 + ___ prompt; and page 21 includes 3 + 6 + 5 although no pair totals ten. Select or adapt these items before independent work.

Teaching tips & learning objectives

Learning objectives

Decompose an addend to make a ten when adding two single-digit numbers
Complete a ten frame and write the matching addition equation
Identify which two of three given numbers combine to make ten

Teaching tips

Introduce with the ten-frame pages first, since the dot visual supports the more abstract make-a-ten equations that follow.
Use the final missing-addend-to-10 pages as a quick daily warm-up to build the automatic ten-combinations the make-a-ten strategy depends on.
Select or adapt conflicting prompts on pages 1, 13–14 and 21 before assigning them; some do not support the stated make-ten step.

Skills covered

Make-a-ten addition strategy — students decompose one addend to complete a ten before adding the remainder, e.g. 8 + 6 becomes 10 + 4.
Ten-frame representation — students complete dot ten frames and translate the visual into a written equation.
Three-addend combinations — students circle two numbers from a set of three that combine to make ten before solving the full sum.

Good to know

Questions teachers ask about this resource

What should I model first?

Use objects or a ten frame to show how part of one addend completes ten, then connect that action to the written equation.

Curriculum

Standards, concepts & topics

Standards

1.OA.C.6 — Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
