Let k≥3 . We prove the following three bounds for the matching number, α′(G) , of a graph, G, of order n size m and maximum degree at most k. If k is odd, then α′(G)≥(k−1k(k2−3))n+(k2−k−2k(k2−3))m−k−1k(k2−3) . If k is even, then α′(G)≥nk(k+1)+mk+1−1k . If k is even, then α′(G)≥(k+2k2+k+2)m−(k−2k2+k+2)n−k+2k2+k+2 .
